Original scientific paper Authorizing can be described as an endogenous system signal that determines whether a job release is allowed or not. Whereas job releases are scheduled in push systems, they are authorized in pull systems since pull-type manufacturing systems are controlled by downstream information. Traditionally, process planning and authorizing are regarded as separate tasks perform...

Process planning and scheduling are two of the most important functions in modern manufacturing system. Considering their complementarity, integrating them more tightly can improve the performance and productivity of the whole manufacturing system. Meanwhile, the multi-objective optimization problem is widespread existing in manufacturing system. In this paper, an effective genetic algorithm is...

We propose a new integrated architecture for distributed planning and scheduling that exploits constraints for problem decomposition and coordination. Our goal is to develop an efficient method to solve densely constrained planning / scheduling problems in a distributed manner without sacrificing solution quality. We implemented a prototype system, called CAMPS, in which hierarchy of intelligen...

Since there has been tremendous progress in planning and scheduling in the process industry during the last 20 years, it might be worthwhile to give an overview of the current state-of-the-art of planning and scheduling problems in the chemical process industry. This is the purpose of the current review which has the following structure: we start with some conceptional thoughts and some comment...

Low volume production associated with space systems manufacturing is inherently expensive, time-consuming, and risk-laden. At the root of this problem is an inability to adequately predict, monitor, and control the product development and sustainment process. This paper describes the ASSIST system, an intelligent knowledge management system designed to address inefficient information management...

Real problems require the combination of time and resources management. In the last decade, different approaches that integrate planning and scheduling have appeared. In this paper we present PIPSS, a system that combines traditional state space search planning with constraint satisfaction algorithms for scheduling, so that it can also reason about temporal and multicapacity resources problems....

This paper addresses the integrated planning/scheduling of chemical supply chains (SC) with multi-product, multi-echelon distribution networks taking into account financial management issues and suggests a novel approach for enterprise wide management. In order to tackle this problem, it is derived a mathematical formulation combining a scheduling/planning model with a cash flow and budgeting f...
