Article
Trying to answer industrial challenges regarding production planning and control, Ptak and Smith propose a new method called Demand Driven MRP. Their basis is to cope with variability instead of facing it. Amongst the different key points of the method, buffer location choice is not clearly defined. We aim to investigate its impact on the industria...
Conference Paper
This work proposes a framework based on a discrete event simulation to evaluate Demand Driven MRP (DDMRP) performances in both in-vivo and in-vitro experiment. The target is to use exactly the same modeling environment to evaluate particular points risen in industrial cases. As industrial cases often present a high level of complexity, it is challe...
Conference Paper
The new economical context is qualified as VUCA (Volatile, Uncertain, Complex and Ambiguous) which leads to the ineffectiveness of traditional supply chain management methods. Facing this situation, Ptak and Smith (2011) propose the Demand Driven MRP (DDMRP) as a solution to deal with it combining proven methods with innovations. Our review of indu...
Article
One of the major challenges in industrial production is to efficiently design or redesign a competitive manufacturing system (MS), as the associated decision-making process is very complex. The scenario of Industry 4.0, with rapid changes in key factors such as technology and costumer demand, has made such process even harder, and the need to struc...

Cet article porte sur l’évolution des modes de pilotage industriels et l’impact du choix sur les performances, notamment financière. La plupart des entreprises adoptent un mode de planification basé sur les principes du MRP2 qui datent de la fin des années 70’. Force est de constater que les conditions de l’environnement économique ne sont plus les...

Flow lines are widely used in mechanical industry. They consist to a set of workstations through which parts are manufactured. Designing such a line is a very complex problem due to manufacturing and design constraints and to the large number of possible decisions. Usually, the design of this type of production lines involves the selection of the n...

Full-text available
Here we discuss a multi-product lot-sizing problem for a job shop controlled with a heijunka box. Demand is considered as a random variable with constant variation which must be absorbed somehow by the manufacturing system, either by increased inventory or by flexi-bility in the production. When a heijunka concept (production leveling) is used, flu...
Article
We consider a stochastic multi-product sequencing and lot-sizing problem. The two following types of uncertainties are taken into account: random lead time due to machine breakdowns and random yield because of rejects. It is assumed that there is a sequence dependent setup time between lots of different products. The goal is to maximize the probabi...
Article
Full-text available
A single-machine multi-product lot-sizing and sequencing problem is studied. In this problem, items of n different products are manufactured in lots. Demands for products as well as per item processing times are known. There are losses of productivity because of non perfect production. There is also a sequence dependent set-up time between lots of...
Article
Full-text available
The paper deals with a stochastic multi-product sequencing and lot-sizing problem for a line that produces items in lots. Two types of uncertainties are considered: random lead time induced by machine breakdowns and random yield to take into account part rejects. In addition, sequence dependent setup times are also included. This study focuses on m...

A single machine multi-product lot-sizing and sequencing problem for a single period is studied. In this problem, n different product types are manufactured in lots. A demand for good quality items as well as a per item processing time are known for all product types. There is a sequence dependent set-up time between lots of different types. Machin...

The globalisation of markets and worldwide competition forces manufacturing enterprises to enter into alliances, leading to the creation of distributed manufacturing enterprises. Before forming a partnership, it is essential to evaluate the viability of a proposed manufacturing network. This paper presents a generic simulation model that attempts t...

This paper deals with the multi-product lot-sizing and sequencing problem under uncertainties. The production line considered contains several machines placed sequentially (a flow-shop). It is assumed that each machine can process defective items (yield for each product is random), also it can breakdown. The time between breakdowns and repair times...

Chapter
Full-text available
This chapter addresses the problem of optimal lot-sizing and sequencing of manufacturing items under uncertainties. A state of the art is presented and a case study is developed. For the case study, the following factors are taken into account: processing and set-up times, random machine breakdowns and rejects. The goal is to minimize the cost and...
Article
The purpose of this paper is to propose and compare several optimization methods for elective surgery planning when operating room (OR) capacity is shared by elective and emergency surgery. The planning problem is considered as a stochastic optimization problem in order to minimize expected overtime costs and patients' related costs. An "almost" ex...
Article
Full-text available
This paper describes a stochastic model for Operating Room (OR) planning with two types of demand for surgery: elective surgery and emergency surgery. Elective cases can be planned ahead and have a patient-related cost depending on the surgery date. Emergency cases arrive randomly and have to be performed on the day of arrival. The planning problem...
Conference Paper
To remedy lacks in modeling and analysis of health care flow, we present in this paper a new modeling methodology for addressing organization problems of health care systems. It is a patient-centered meta-model based on three views : (i) process (pathway of patients), (ii) resource (activity of involved resources), and (iii) organization (resources...

This article treats impact of the assignment of the operators on the machines on the operational times of work and the consequences of these assignments on the admissibility of a scheduling established by taking into account only the machines constraints. After having proposed a model allowing to characterize these impacts and having evaluated the...

This paper addresses Operating Rooms (ORs) planning problem with elective and emergency surgery demands. The planning problem is considered as a stochastic optimization problem in order to minimize overtime costs and patients' related costs. An "almost" exact method combining Monte Carle simulation and mixed integer programming is presented, and co...
Conference Paper
This article deals with the impact of machines operator's assignment on jobs processing times in workshop scheduling problems. We are interested to the case in which the number of operators is lower than the number of machines, operators being able to supervise several machines simultaneously, and operator's assignments affect machines productiviti...

This paper proposes a stochastic model for Operat ing Rooms (ORs) planning with two types of surgery demands: elective surgery and emergency surgery. Elective cases can be planned starting from an earliest date with a patie nt related cost depending on the surgery date. Emergency cases arrive randomly and have to be performed on the day of arrival....

Conference Paper
Full-text available
This paper focuses on the forecasting risk analysis in supply chains with intermittent demand, which is typical for the inventory management of the 'slow-moving items', such as service parts or high-priced capital goods. The adopted demand model is based on the Generalised Beta-Binomial Distribution (GBBD), which is capable of incorporating the add...

We work in complex industrial system simulation on geographical, decisional and informational distri-bution terms.
