Flow shop and job shop scheduling represent two distinct production processes. Flow shop scheduling involves tasks following a fixed, linear sequence across machines, making it ideal for high-volume, repetitive manufacturing. The primary goal is minimizing makespan, cycle time, and idle periods, maximizing throughput efficiency.
On the other hand, job shop scheduling offers greater flexibility, as jobs follow unique operational sequences. This approach is best suited for custom or low-volume production. The key objectives are to minimize makespan, reduce delays, and optimize resource allocation.
In essence, flow shops emphasize efficiency in standardized processes, while job shops prioritize flexibility.

In nanocrystalline metals, the size of their crystalline grains affects how strong, ductile, and hard they are. Smaller grains often mean stronger metals but can reduce ductility. Controlling grain size during manufacturing could help optimize these properties for specific applications.
Relevant answer
Answer
Hello,
- Regarding strength, we have two different cases depending on the grain size:
1- Hall-Petch Relationship: This relationship states that as the grain size decreases, the strength and hardness of the metal increase. This is because grain boundaries act as barriers to dislocation motion, making it harder for the material to deform.
2- Inverse Hall-Petch Breakdown: At extremely small grain sizes (typically below 10-15 nm), the strengthening effect can reverse. This is due to mechanisms like grain boundary sliding becoming more prominent, leading to softening.
- Concerning ductility, nanocrystalline metals can become more brittle because there are fewer dislocations within the grains to allow for plastic deformation.
- To make a balance between strength and ductility, having a bimodal grain size distribution could be a solution, with both small (for example, 10-20 nm) and slightly larger grains (more than 100 nm up to 1-2 µm). This can improve ductility while maintaining high strength. The very small grains contribute significantly to the strength of the material due to the Hall-Petch effect while the slightly larger grains enhance ductility by providing pathways for dislocation movement and accommodating more plastic deformation without leading to premature failure.
Hope this helps.

Am I in the middle of synthesizing Maxine flakes? Or have I made a mistake in the manufacturing process?
Relevant answer
Answer
The conversion of Ti3C2 colloid to Ti3C2 2D flakes involves the further exfoliation of Ti3C2 particles into thin sheets.
This can be achieved through a variety of methods, including liquid-phase exfoliation, mechanical exfoliation, and chemical vapor deposition..
Liquid-phase exfoliation is the most commonly used method for the conversion of Ti3C2 colloid to 2D flakes.
In this method, the Ti3C2 colloid is sonicated in a suitable solvent to further exfoliate the Ti3C2 particles into thin sheets.
The solvent used for liquid-phase exfoliation plays a crucial role in the final quality of the 2D flakes.
Common solvents used for liquid-phase exfoliation of Ti3C2 colloid include N-methyl-2-pyrrolidone (NMP), dimethylformamide (DMF), and water.
The resulting Ti3C2 2D flakes can be characterized using techniques such as scanning electron microscopy (SEM) and transmission electron microscopy (TEM)..
Mechanical exfoliation involves the use of mechanical force to exfoliate Ti3C2 colloid into 2D flakes.
This method is less commonly used due to its low yield and time-consuming nature.
In this method, the Ti3C2 colloid is deposited onto a suitable substrate, and a sharp object such as a tape or a blade is used to mechanically exfoliate the Ti3C2 particles into thin sheets..
Chemical vapor deposition (CVD) is another method used for the synthesis of Ti3C2 2D flakes.
In this method, a Ti3C2 precursor is deposited onto a suitable substrate, and a reactive gas such as hydrogen is introduced.
The precursor reacts with the gas to form Ti3C2 2D flakes on the substrate.
This method is more complex and expensive compared to liquid-phase exfoliation and mechanical exfoliation.

How can current issues in both conventional and solid-state additive manufacturing processes? What are the various metallurgical solutions available for effectively eradicating interlayer defects in additive manufacturing?
Relevant answer
Answer
Both conventional and solid-state additive manufacturing processes have their own set of issues. Some of the current issues in conventional additive manufacturing processes include poor surface finish, poor accuracy, and limited design complexity. On the other hand, solid-state additive manufacturing processes suffer from issues such as residual stresses, anisotropy, and interlayer defects.
Interlayer defects are one of the most significant issues faced in additive manufacturing. These defects can result in poor mechanical properties, lower product quality, and even product failure. There are several metallurgical solutions available for effectively eradicating interlayer defects in additive manufacturing. Here are a few examples:
  1. Heat treatment: Heat treatment is one of the most common metallurgical solutions used to eliminate interlayer defects. It involves heating the product to a specific temperature and holding it there for a certain amount of time. This process can help to relieve residual stresses and minimize the formation of interlayer defects.
  2. In-situ process monitoring: In-situ process monitoring involves monitoring the manufacturing process in real-time. This allows for any defects or issues to be identified and addressed immediately. This can help to prevent the formation of interlayer defects and ensure product quality.
  3. Material selection: The selection of the appropriate material can also play a significant role in eliminating interlayer defects. The material's properties, such as its melting temperature and viscosity, can affect its behavior during the manufacturing process. Choosing a material with suitable properties can help to minimize interlayer defects.
  4. Process parameter optimization: The optimization of process parameters such as temperature, layer thickness, and feed rate can also help to reduce interlayer defects. Fine-tuning these parameters can help to improve product quality and reduce the formation of defects.
Overall, the effective eradication of interlayer defects in additive manufacturing requires a combination of metallurgical solutions. By implementing a range of solutions such as heat treatment, in-situ process monitoring, material selection, and process parameter optimization, it is possible to significantly reduce interlayer defects and ensure high-quality products.

Dear Aashlesha,
yes, you can if you have accurate input-output data for material- and energy flows in units. In this case, you can build an LCA process for this (LC Inventory), even in a free demo version of GaBi. You can build an LCA plan on this LCA process, which will run analytical data on emissions, primary energies, environmental impact categories. Since you would perform this analysis for only the production stage, delimit the system from cradle-to-gate beforehand.

Advanced Manufacturing-3D printing-paradigm shift -social impacts
Relevant answer
Answer
Since the 1980s when Chuck Hull proposed 3D printing, there has been a change in way of building.
Additive manufacturing, so well known to mankind, has earned ally of 3D printing (3D printing is additive manufacturing, but additive manufacturing is not just 3D printing).
The advances come from possibility of building parts, and items that Subtractive and Formative Manufacturing are unable to meet.
The manufactures complement each other and one manages to do what the other does not.
The paradigm shift has been taking place in last 40 years, with more force from 2010 to the present day. See new machines, new materials, new ideas!
The impact on society starts in manufacturing process in Additive Manufacturing, which is insertion of material (raw material) to make the object, without wasting material. This is significant for product cost, environment and nature.
Additive Manufacturing contributes to more agile solutions and prototyping with reduced cost. This directly impacts the cost of developing a product and thus its final cost.

Dear Student Rashad Filfilan ,
Yes it's true! You cannot perform your practical research.
Yes is true! Some industrial machines are on all the time, but this is generally not the case with CNC, unless they need some kind of heating in cold countries.
However, in the case of CNC machines, I have a doubt that they need to be on all time and thus, I do not believe that they use electricity in idle periods, in end, they do not need to be turned on. Unless very large machines, which needs to be verified.
If so, is it possible for manufacturers to have given it in their catalogs? It is worth checking.

We approve (or disapprove) various supplier raw material changes in our company and the steps we take to approve the change is a function of whether or not there is a material change (some changes are just process changes, location changes, or sub-supplier changes).
We always enter a gray area when it comes to CAS numbers in determining whether or not there is a material change. Below is an example.
We purchase Material Z from Supplier A that contains Ingredient X that Supplier A purchases from Sub-Supplier B. Sub-Supplier B is going out of business, so Supplier A will purchase Ingredient X from Sub-Supplier C. Supplier A states that their formulation of Material Z will be the same and that the CAS number of Ingredient X will be the same.
Is this enough information to state that the materials are identical?
I did some research and found this, so wanted to see if anyone here had more detailed knowledge of the subject and can confirm or deny that the below statement is accurate?
"The CAS number being the same does mean that it is the exact same molecule, but it does not necessarily ensure the material is identical. Because they could have slightly different concentrations or even different manufacturing processes, which could lead to different impurity profiles."
Thanks much, Mike

I’ve recently come across some silicone suction cups that are labeled as non-marking. I’m wondering what makes these suction cups different from other silicone suction cups? I’m sure it has to do with free oligomers but I’m curious if there is anything specifically different in the manufacturing process or the chemistry behind it.
Relevant answer
Answer
You are thinking correctly. They are typically molded without any mold realease agent. Over time these mold release agents can leach out and their chemistry can affect surfaces, especially if it will be painted later on..
The other characteristic is the shape of the cup itself. It needs to be near perfect in order yield to good vacuum distribution and avoid any deformation of the subtrate /surface.

Tunas Manja Group operates the retail stores known as TMG Mart that provides and sells various products which are mainly the groceries and houseware goods. However, the mart is facing problems in finding the best solution for sorting process which caused the customers having a hard time finding their desired items in the mart.
Relevant answer
Answer
Dear Hidyah,
In simple terms, the five S methodology helps a workplace remove items that are no longer needed (sort), organize the items to optimize efficiency and flow (straighten), clean the area in order to more easily identify problems (shine), implement color coding and labels to stay consistent with other areas (standardize) and develop behaviors that keep the workplace organized over the long term (sustain).
5S – 5S stands for Sort, Set, Shine, Standardize and Sustain. It’s a simple but powerful way to organize a workspace that reduces waste and boosts productivity. Sorting is often a first step for many companies because of the immediate impact on workflow and the elimination of the Eight Wastes focused on by Lean.
Sort (seiri) – Distinguishing between necessary and unnecessary things, and getting rid of what you do not need
· Remove items not used in area – outdated materials, broken equipment, redundant equipment, files on the computer, measurements which you no longer use
· Ask staff to tag all items which they don’t think are needed – this improves understanding about need and use
· CLASSIFY ALL EQUIPMENT AND MATERIALS BY FREQUENCY OF USE TO HELP DECIDE IF IT SHOULD BE REMOVED – PLACE ‘RED TAG’ ON ITEMS TO BE REMOVED
(please note this is)
· Establish a ‘holding area’ for items that are difficult to classify – hold item for allotted period to enable others not on 5S team to review
Bold and uppercase points are valid for optimizing and sorting in hypermarket.
For further study on commercial mall, use this site to read.

Hope it helpful for you.

Hi everyone!
I have designed something related to Jigs & Fixtures (which is related to Mechanical Engineering/Manufacturing Process). I have created Single Locator (which is cylindrical in shape and attached to the wall) and called it Six times in my assembly design. There is a Point contact between Rectangular block and these 06 Locators (Locators are attached in 3-2-1 configuration). Now I am applying Load on "-z","-y" & "-x" axes and I want this rectangular block to slide over the cylindrical surface of Locators. But Locators are actually displacing along with Rectangular block (and simulation is acting like, point of contact/nodal contact between rectangular and cylindrical surface is fixed due to which Rectangular block is dragging the Cylindrical Locators along with it.
P.S: Rectangular block is rigid body. Locators are rigid but they can/should displace AXIALLY only and No rotation No non-axial movement is/should be allowed. If I try to make locators rigid, just like a Rectangular block, the Rectangular block will not displace at all (just because, as I said earlier, the point of contact will act like a fixed contact and as a locator cant move, so it will not allow Rectangular block to slide freely on it either).
Help will be much appreciated.

Answer
Hi Chloe,
HILIC and Ion-pairing chromatography (IPC) are commonly used approaches so you may be able to find protocols that would fit your needs.
Personally, I recommend Aqueous Normal Phase mode (Distinct from HILIC or organic normal phase). Most of the time, ANP can be employed without derivatization procedure and with mobile phases as simple as H2O + 0.1% formic acid (A) & Acetonitrile + 0.1% formic acid (B). Only the TYPE-C(TM) Silica Hydride columns from MicroSolv (https://mtc-usa.com/cogent_order) can achieve this mode of separation, but it is a good long-term investment. I recommend using Cogent Diamond Hydride column for polar molecule retention.
I hope this helps and good luck.

We are a manufacturer of active pharmaceutical ingredients(API) and testing the elemental impurities as per ICHQ3D guide line.In ICHQ3D there is list of 24 elements they have to be tested with some recommendation and apart from that if any elements is used as a catalyst or as a raw material has to be also tested.If we talk about Calcium ,Sodium and Phosphorus they are abandoned in nature and are being in primary stages of manufacturing process.
Relevant answer
Answer
No, they are not in the list in ICH Q3D. In addition the requirement is for the drug product at the NDA stage. Some buyers request that your API be tested for the 24 elemental impurities and is a good practice for business. Also, it they are controlled at the API (and excipient) stage, it could be included in the justification not to control it for the drug product. The sponsor of the NDA is responsible to provide information of the elemental impurities and a justification for the levels outside the ICH limits, Also, if some metal ions like Ca2+ could change the performance of the drug product it has to have specification limits, but not as per ICH Q3D.

Manufacturing systems vary in various aspects like size, product variety, automation level, layout, production control etc. and it gets quite challenging to fit a model which caters to all the manufacturing systems. So, what are the most robust and widely applicable modeling and analysis techniques in the domain of manufacturing systems?
Relevant answer
Answer
Yes, manufacturing systems are all vary in its size, product variety, automation level, layout, etc, etc. However, I believe, that the best universal methodology to address all these and many other issues is discrete event simulation modeling.
The power of discrete event computer simulation (DES) modeling is its capability of testing multiple scenarios of changing the complex highly variable process without disruption your current process in order to see what steps are the largest waste, where to focus your efforts for improvement, whether the suggested change will really result in the desired improvement and how much.
DES is the most robust and widely applicable modeling and analyzing technique both in manufacturing and in many other industries: healthcare, finance, retail, etc.
DES has become indispensable and demonstrated its power and efficiency for years in addressing such problems as: - Capacity: How many pieces of equipment of various type are required for the manufacturing shop? - Staffing: How many mechanics, workers and other personal are needed for a particular shift in a unit (department) in order to best achieve operational and performance objectives? - Scheduling: What are the optimized staff schedules that help not only in operational efficiency but also take into account staff preferences and convenience?
-What is the optimal equipment maintenance schedule? - Work pieces flow: Is there a bottleneck formed and at what piece of equipment that hamper production throughput goals? - Resource allocation: Is it more efficient to use specialized resources or pooled (interchangeable) resources (say, oven, equipment, and staff)? Does it make economic sense to keep some product lines (or drop them at all)? -- Optimized facilities layout - Design of the facility optimized workflow Also, the Forecasting methodology: How to forecast and play different scenarios with the future product volumes (demand) for short- and long-term planning and scheduling purposes?
Developing a simulation model for the entire facility requires some time and efforts, but such an investment will also be justified as an indispensable tool as a digital twin of the manufacturing process/facility, provided that the model is properly validated and verified.

i am working on hierarchical decision making problem. factor's at each level of hierarchy are not completely independent, some of them are independent and some are dependent on other factors (more than one ) so there is a degree of dependence between factors at each level.
please suggest methods and tools to evaluate this inter-dependence.
Relevant answer
Answer
Dear Mr Gani,
In case you are working with subjective decision models as mentioned by Mr Greg Oslen, you may try methods like DEMATEL or ISM for mapping the inter-relationships between the factors. In fact, ISM provides two scores to each factor namely driving and dependence powers with respect to other factors considered in the model. Furthermore, through a MICMAC analysis, you may also cluster the factors into four classes according to their relative importance.

I want to perform a study on volumetric shrinkage and strength after manufacturing the part through additive manufacturing process. Now I am searching a potential application for this analysis. Can anybody help me?
Relevant answer
Answer
in industry additive manufacturing is getting momentum, but often the process is applied to second-level parts not high performance / performance critical parts. The major drivers are aircraft and car industries at the moment. One of the major materials (pushed by aircraft companies) is TiAl6V4 which is analysed best and widely applied. Of course there are already other material as well. However depending on the type of additive manufacturing process there are more or less pores in the structure. TiAl6V4 shows very high toughness also at higher temperatures, but the porosity will reduce the strength of the material and the often required thermal treatment causes part shrinkage. I think the manufacture of small batch high performance part production (gears, even special barings) will change the manufacture chains of these parts as competition, manufacturing lead-time and costs will make up for possibly higher prices per part. It has been reported that some part suppliers / manufacturers in car industry have begun to print (plastic and/or metal) parts for older cars / machines rather than keeping large stocks of spareparts over many years.

thank you for your comment. However, let my respectfully disagree with these concepts not being integrated in practice - especially we see this integration in practise already.
Would it make sense to carry out Value Stream Analysis on tablets instead of paper + pen? --> Lean Management suggests that VSA should be done with paper and pen. So my question would be if using digital media to foster Lean Management approaches is not helpful? And would that not mean an integration?
If you read the official definition of Industry 4.0 (e.g. from the German platform 4.0) you will find that I4.0 does not define itself through AI-concepts neither does I4.0 aim for the development of products or services - it aims for more efficient value creation through integration to create customer benefits.
I do not see the concepts of Industry 4.0 an more generic than the ones coming from lean management.
My suggestion would be to keep an open mind and not try to block such integrations and developments - in the end we are in the field of industrial engineering or similar, and there everything that helps companies in practise seems right - it is not an exact sience!
