Under stochastic demand and deterministic processing times, we discussed a single-part JIT production system with the production-ordering and supplier Kanbans and derived the stationary distributions of the backlogged demand. In this paper, we extend the system to a multi-part JIT production system, deterministic processing times and withdrawals with lead time. These conditions are more realist...

The purpose of this study is to identify and evaluate the scale of implementation of Just-In-Time (JIT) in the different industrial sectors in the Middle East. This study analyzes the empirical data collected by a questionnaire survey distributed to companies in three main industrial sectors in the Middle East, which are: food, chemicals and fabrics. The following main hypotheses is formulated ...

The customer oriented market leaded to the growth of complexity of production and service processes. This growing complexity has increased the required logistics operations and leaded to the appearance of global supply chain strategies. There are several supply strategies, which are based on just-in-time philosophy and they are core tools of leaning. One of these JIT-based supply strategies is ...

In manufacturing, great gains in performance have been realized by a new production philosophy, which leads to "lean production". This new production philosophy is a generalization of such partial approaches as JIT, TQM, time-based competition, and concurrent engineering. In construction, lean production is little known. The concepts, principles and methods of lean production are reviewed, and ...

Many factors affect JIT implementation directly or indirectly. Factors such as product quality and lead time directly affect the implementation of JIT. On the other hand, factors such as work environment, working conditions, motivation, flexibility whether manufacturing or organizational affect JIT implementation indirectly, although their impact is no less important than those affecting direct...

In this paper, we develop a joint quality control and preventive maintenance policy for a production system producing conforming and non-conforming units. The considered system consists of one machine which must supply another production line operating on a just-in-time basis. According to the proportion l of non-conforming units observed on each lot and compared to a threshold value lm, one de...

In this paper, the hybrid production planning & control method Double Speed Single Production Line (DSSPL) is presented, modeled and its performances evaluated and compared to classical Production Planning and Control methods (PPC). DSSPL combines JIT/kanban and Material Requirement Planning for the production of different classes of products (Aand B-items based on a market or customer oriented...

this research presents a new application of the cloud theory-based simulated annealing algorithm to solve mixed model assembly line sequencing problems where line stoppage cost is expected to be optimized. this objective is highly significant in mixed model assembly line sequencing problems based on just-in-time production system. moreover, this type of problem is np-hard and solving this probl...
