Dynamic scheduling in manufacturing systems using Brownian approximations

Dynamic scheduling for agent based manufacturing systems

Purpose: Development of the decision making architecture for the multi-agent societies with temporal restrictions. General ideas for the necessary architecture based on the blackboard one is presented. Design/methodology/approach: Fuzzy logic approach that makes it possible to reach suboptimal solutions within the acceptable timeframe. Development of the relevant systems calls for compiling the...

Scheduling in manufacturing systems

A survey of dynamic scheduling in manufacturing systems

In most real-world environments, scheduling is an ongoing reactive process where the presence of a variety of unexpected disruptions is usually inevitable, and continually forces reconsideration and revision of pre-established schedules. Many of the approaches developed to solve the problem of static scheduling are often impractical in real-world environments, and the near-optimal schedules wit...

Dynamic setup scheduling and flow control in manufacturing systems

In this paper we propose a method for flow control of parts in a manufacturing system with machines that require setups. The setup scheduling problem is investigated in the context of a multilevel hierarchy of discrete events with distinct frequencies. The higher level of the hierarchy calculates a target trajectory in the surplus/backlog space of the part types which must be tracked at the lev...

Dynamic Scheduling of Manufacturing Systems with Setups and Random Disruptions

Manufacturing systems are often composed of machines that can produce a variety of items but that most undergo time-consuming (and possibly costly) setups when switching between product types. Scheduling these setups efficiently can have important economic effects on the performance of the plant and involves a tradeoff between throughput, inventory, and operating costs. In addition, the schedul...
