We consider the production of multiple standardized products on a single machine with limited capacity and set-up times under random demands and random production times, i.e., the so-called stochastic economic lot scheduling problem (SELSP). The main task for the production manager in this setting is the construction of a production plan for the machine that minimizes the total costs, i.e., the...

in this paper, the unified power flow controller (upfc) is enhanced with a chaotic particle swarm optimization (cpso) damping controller in order to mitigate the low frequency oscillations (lfo) in a single machine infinite bus (smib) power system. the designed damping controller is an optimized lead-lag controller, which extracts the speed deviation of the generator rotor and generates the out...

In this paper, we study an economic production quantity (EPQ) problem in which an item is produced by a single machine. We assume that the machine may fail in an exponential random time. The repair time is an exponential random variable. It is possible to satisfy the demand from an outside supplier when the machine is failed. The objective is to determine the production and order quantities in ...

In this paper, we deal with the problem of balance between two alternative modes for production: in-house production and outsourcing, under a combined approach of maintenance management and production control in multi-periods plan. The considered production system consists of a single randomly failing and repairable machine producing a single product. The production system aims to satisfy the m...

The recent trend toward mass customization has increased the demand for multiproduct/multivolume production and driven a need for autonomous production systems that can respond quickly to changes on production lines. Production facilities using cameras and robot-based image recognition technologies must also be adaptable to changes in the image-capturing environment and product lots, so technol...

In this paper, product parts and machine agents are proposed for the configuration of an autonomous flexible assembly system. Product parts are divided into two types. One is the main part that is a base of the assembled product and the other is for sub parts that are installed on the main part. These parts and assembly machines are implemented as software agents in a virtual assembly productio...

Concurrent computing environments based on loosely coupled networks have proven effective as resources for multiprocessing. Experiences with and enhancements to PVM (Parallel Virtual Machine) are described in this paper. PVM is a software system that allows the utilization of a heterogeneous network of parallel and serial computers as a single computational resource. This report also describes ...

We consider the problem of dynamically allocating production capacity between two products to minimize the average inventory and backorder costs per unit time in a make-to-stock single machine system. Using sample path comparisons and dynamic programming, we give a characterization of the optimal hedging point policy for a certain region of the state space. The characterization is simple enough...
