We consider the situation of a supplier plant whose customer plants desire just-in-time (JIT) deliveries. Randomness in both the production and demand processes make satisfying every demand that might occur in true JIT fashion impossible. Therefore, supplier plants typically negotiate bounds on...

A quadratic model for production-inventory planning was made famous by Holt, Modigliani, Muth, and Simon in 1960 in [3], especially for its application to a paint factory. A discrete control version of a related quadratic production-inventory model was studied by Kleindorfer, Kriebel, Thompson,...

Sarkar and Zangwill (S-Z, [Sarkar, D., W. I. Zangwill. 1991. Variance effects in cyclic production systems. Management Sci. 37(4, April) 444--453.]) have shown that in the presence of variance, setup and processing time reductions can have "detrimental" effects on the work-in-process (WIP)...

This paper investigates the problem of sequencing N products on an assembly line with two objectives: minimizing (1) the risk of conveyor stoppage and (2) the total utility work. For a single station with arbitrary processing times, this problem is proved NP-hard in the strong sense for each of...

We provide a new formulation and solution procedure to sequence a mixed model just-in-time (JIT) assembly system. Mixed model JIT assembly systems are a fundamental part of the well-known "Toyota Production System." The underlying idea in sequencing these systems is to maintain a constant usage...

This paper provides an economic rationale for modern manufacturing control practices such as the minimal inventories in Just in Time (JIT)systems, zero-defect policies, and continuous improvement. The popular and academic literature contains descriptive studies on the mechanics of these systems...

Experimental evidence suggests that production-line workers adjust their work rates in certain situations to prevent idle time. We refer to this as state-dependent behavior, in contrast to the state-independent behavior of machines. In this paper, we develop several models for the...

We investigates the degree to which increasing vertical information integration using Electronic Data Interchange technology enhances shipment performance of suppliers in a Just-in-Time environment. Our analysis of shipment data in the automobile industry suggests that shipment performance...

We consider a supply chain in which two suppliers compete for supply to a customer. Pricing and delivery-frequency decisions in the system are analyzed by two three-stage noncooperative games with different decision rights designated to the parties involved. The customer first sets the price (or...
