Cost, quality, patient satisfaction etc. are some important issues facing healthcare industry. Hospitals are searching continuously for innovative ways to contain costs without sacrificing quality and meet the patients’ needs. One successful solution has been the adoption of JIT manufacturing systems which involve many functional areas of a company such as manufacturing, engineering, marketing,...

In this paper we consider production economic and cost related yield rate in a JIT (Just in Time) system. Based on the traditional EPQ (Economic Production Quantity) model, we establish the relation between cost and yield rate. The geometric programming approach is applied in our model to solve this optimizing posynomials problem. A numerical example is carried out to verify the proposed model....

Just-In-Time (JIT) is a lean manufacturing tool, which provides the benefits of efficiency, and of minimizing unnecessary costs for many organisations. However, the risks arising from these benefits have been disregarded. These risks impact on system processes disrupting the whole supply chain. This paper proposes an inventory model that can simultaneously reduce costs and risks in JIT systems....

Implementing lean manufacturing concepts is essential for companies in the manufacturing and service industries to survive in the very competitive global marketplace. A key point is to eliminate waste while delivering value to the customers. Thus, graduates from engineering programs such as manufacturing, industrial and systems engineering and engineering management must be able to focus and ap...

A fuzzy graph is a symmetric binary fuzzy relation on a fuzzy subset. The concept of fuzzy sets and fuzzy relations was introduced by L.A.Zadeh in 1965cite{zl} and further studiedcite{ka}. It was Rosenfeldcite{ra} who considered fuzzy relations on fuzzy sets and developed the theory of fuzzy graphs in 1975. The concepts of fuzzy trees, blocks, bridges and cut nodes in fuzzy graph has been studi...

Although change management panaceas have been widely discussed in the business and management literature for several decades, not many publications address the role of simulation modeling in supporting these panaceas. This paper investigates four management innovation and change programs: TQM, JIT, BPR and Process Innovation and discusses how simulation modeling could increase their effectivene...
