A just-in-time production system was founded by Toyota Motor Corporation. A broad definition of JIT is that only the right amount of necessary goods are supplied in the right place at the right time. Keeping the rate of each part used constant (parts usage leveling goal) is the most important goal in assembly scheduling of mixed-model products in JIT production system. Since the goal-chasing method was proposed, a number of papers have dealt with this problem. The purpose of the JIT production system, however, is not only to reduce inventory levels, but also to reduce inventory costs and increase profits. Until now, this subject has not been discussed in any JIT research. Therefore, in this paper, we propose a new heuristic method for different part compositions and different parts prices in mixed-model assembly scheduling at a single work-station. It is based on a price-based goal-chasing method to decrease variations in the purchasing cost of parts. The main contribution of this paper is that we do not only consider the quantity of parts, but also the purchase price of the parts. A large number of better results shows the effectiveness of the proposed heuristic method through numerical experiments.

This paper presents a scheduling method to maximize total profit as a performance measure in a two-stage flow shop model. The profit is defined as the difference between the revenue and the cost of production, and a scheduling method to maximize total profit is proposed using the Branch and Bound method aiming at maximizing revenue and minimizing costs. This paper compares the optimal schedule which maximize total profit with the optimal schedule which minimize total flow time searched by Johnson's theory. This paper also shows the usefulness and some characteristics of the proposed method through various numerical experiments.

Various scheduling methods have been proposed in order to minimize total flow time or total actual flow time, and thereby promote efficient production. However, such methods are not so effective to maximize company profit, given that requests from customers and the prices of products have grown widely diversified in recent years. In such a case, it must be determined whether the profit can be maximized when both flow times are minimized. This paper proposes an optimal scheduling method which maximizes total profit as a performance measure in a single machine model. Our computational experiments show the usefulness and characteristics of the proposed method.
