The product quality is very important for long-term survival of a company. Therefore, the question of how much quality is enough seems relevant. During the late 1970s and early 1980s, the common answer of this question in western countries was to accept a small but allowable amount of poor quality in outgoing manufactured goods. The Japanese during same time chose a different course of action c...

Three types of JIT ordering systems used for supply chain management were quality tested, the Kanban, the original constant work-in-process (CONWIP), and a synchronized CONWIP. The synchronized CONWIP system is described for its ability to handle complicated supply chains, which consist of assembly stages with different lead times. In the system, orders for each process are released while adjus...

Just in Time (JIT) is a system designed to make an organization operate efficiently and with a minimum number of human and mechanical resources. JIT also improves quality, reduces inventory levels, and provides motivation to solve problems as soon as they occur. JIT can be defined as a system designed to eliminate waste in an organization. Waste is anything that does not add to the value of the...

Two aspects of regime-change management are transitory planning, which avoids assembly feed-stock shortages in the new processing regime, and the timing of the change, which enhances the meshing of adjacent plans. In this paper, the stock implications of regime changes which incorporate transitory planning, are optimised with respect to the timing of the change. To highlight the stock effect, p...

The UA Indigenous Governance Program is an educational partnership between two units, the Native Nations Institute [4] (NNI) at the Udall Center for Studies in Public Policy [5] and the Indigenous Peoples' Law and Policy Program [6] (IPLP) at the James E. Rogers College of Law [7]. In 2018, its three-week JIT event offers fourteen different courses, ranging from Indigenous Food Sovereignty [8] ...

Though increasing usage of just-in-time (JIT) practices is reported, academics—including Shapiro at Harvard Business School, Karmarkar at UCLA (Anderson) and Cusumano at MIT (Sloan)—as well as a number of practitioners have warned against the unrestricted pursuit of just-in-time practices. They suggest that pure JIT is appropriate only for limited economic environments, that it is ineffective i...

Studies of sick pay and absenteeism have traditionally treated absence as a worker-related phenomenon. There are good reasons to suppose, though, that firms’ incentives to control absenteeism are not uniform. This paper presents what we believe to be the first evidence for relationships between the nature of a firm’s production method ) and its personnel policies, particularly as they are direc...

This paper concerns the modeling of low inventory lines. Currently, most models assume that processing times are independent. We consider the differences in behavior of workers in lowand high-inventory production lines. Using a laboratory experiment we show that workers speed up when they are the cause of idle time on the line. This means that processing time distributions are not independent o...

Recently Just-In-Time (JIT) production has attracted increasing interest throughout the Chinese manufacturing industries and its programs have been widely implemented. Currently, there are few studies conducted about JIT manufacturing implemented by small manufacturing firms in China, even though small firms are still dominant in many areas of manufacturing industries in China. This study analy...

This paper implements the inventory model developed in the first part of this paper in a simplified problem to simultaneously reduce costs and risks in JIT systems. This model is developed to ascertain an optimal ordering strategy for procuring raw materials by using regular multi-external and local backup suppliers to reduce the total cost of the products, and at the same time to reduce the ri...
