Selecting the best remanufacturing or repair strategy for engineering equipment/component is a complex task, partly due to the many factors affecting the decision as well as the high uncertainty associated with these factors. The challenge facing decision makers is to find an effective and reliable approach that supports their decisions regarding t...
This paper presents a framework utilising digital twins for predictive maintenance planning of fuel cells in electric vehicles, focusing on real-time condition monitoring and Remaining Useful Lifetime (RUL) prediction. By integrating advanced algorithms, it optimises maintenance schedules to reduce downtime and extend fuel cell lifetime. Despite re...

Sustainable manufacturing is of great importance in today’s world. In manufacturing, keep industrial equipment well-functioning is important because failure of equipment leads to significant financial and production losses. In addition, disposal of such failed equipment is both costly and environmentally unfriendly and does not recover any residual...
Abstract–With the rapid development of information and sensor technology, the data-driven remaining useful lifetime (RUL) prediction methods have been acquired a successful development. Nowadays, the data-driven RUL methods are focused on estimating the RUL value. However, it is more important to quantify uncertainty associated with the RUL value....
With the rapid development of Industrial 4.0, the modern manufacturing system has been experiencing profoundly digital transformation. The development of new technologies helps to improve the efficiency of production and the quality of products. However, for the increasingly complex production systems, operational decision making encounters more ch...

Industrial equipment/machinery is an important element of manufacturing. They are used for producing objects that people need for everyday use. Therefore, there is a challenge to adopt effective maintenance strategies to keep them well-functioning and well-maintained in production lines. This will save energy and materials and contribute genuinely...
Remanufacturing is an activity of the circular economy model whose purpose is to keep the high value of products and materials. As opposed to the currently employed linear economic model, remanufacturing targets the extension of products and reduces the unnecessary and wasteful use of resources. Remanufacturing, along with health status monitoring,...
Refurbishment and remanufacturing play a vital role in the sustainability of the large industrial field, which aims at restoring the equipment that is close to the end of their life. The EU-funded project RECLAIM proposes new approaches and techniques to support these two activities in order to achieve saving valuable materials and resources by ren...
The study described in this paper addresses the measurement of job satisfaction level of the employees of the University of Benghazi in terms of salary, rewards and promotions, work duties and responsibilities, relationship between leadership and their subordinates, and appreciation and self-esteem. It also investigates the extent of the independen...
In this paper, an intelligent decision support system has been proposed for skin disease diagnosis using a hybrid model of Case-Based Reasoning and Artificial Neural Network techniques. The proposed model uses nine input variables (attributes) that have a major effect on the skin diagnosing process. The output of the model is the diagnosis and the...
Lean technique is very important in the service and industrial fields. It is defined as an effective tool to eliminate the wastes. In lean the wastes are defined as anything which does not add value to the end product. There are wastes that can be avoided, but some are unavoidable for many reasons.
The present study aims to apply the principles o...
Evaluation of educational portals is an important subject area that needs more attention from researchers. A university that has an educational portal which is difficult to use and interact by teachers or students or management staff can reduce the position and reputation of the university. Therefore, it is important to have the ability to make an...

The world’s largest Pre-stressed Concrete Cylinder Pipe (PCCP) water supply project had a series of pipe failures which occurred between 1999 and 2001. This has led the Man-Made River Authority (MMRA), the authority in charge of the implementation and operation of the project, to setup a rehabilitation plan for the conveyance system while maintaini...
Acoustic monitoring has played a major role in the management of one of the world's largest civil engineering projects. After experiencing failures on their pipeline between 1999 and 2001, the Great Man-Made River Authority (GMRA) undertook an aggressive condition assessment program. This program led to the development of a comprehensive Pipeline R...
Many owners of Pre-stressed Concrete Cylinder Pipe (PCCP) water mains around the world experienced failures in their pipelines. The condition and performance of any water pipelines can be assessed by conducting direct inspection (electromagnetic, acoustic monitoring, GPR radar, etc), which when applied to an entire pipeline can be prohibitively exp...
Questions
Question (1)
When normalized fuzzy weights are multiplying the fuzzy numbers so that the resulting fuzzy numbers go outside the range of possible values for a number. This certainly happen because the sum of the upper-bounds of the fuzzy weights are > 1. What do you suggest to tackle this problem (i.e. to emphasize the resulting fuzzy numbers to be inside the range of possible values)?
