Production systems are declarative, in that they do not explicitly specify the control flow. Yet, the concept of a production system does not include the definition of a given control strategy. The control between rules in a production rule program is, in practice, defined by each implementation of a production rule engine. Engines have traditionally been implemented using the Rete algorithm. S...

We consider optimal policies for a production facility in which several (K) products are made to stock in order to satisfy exogenous demand for each. The single machine version of this problem in which the facility manufactures at most one product at a time to minimise inventory costs has been much studied. We achieve a major generalisation by formulating the production problem as one involving...

The paper gives the results of the project that is oriented on the usage of knowledge discoveries from production systems. Knowledge discoveries were used in the management of these systems. The simulation models of manufacturing systems were developed to obtain the necessary data about production. Data mining model was created by using of the specific methods and selected techniques for define...

The paper gives the pilot results of the project that is oriented on the use of data mining techniques and knowledge discoveries from production systems through them. They have been used in the management of these systems. The simulation models of manufacturing systems have been developed to obtain the necessary data about production. The authors have developed the way of storing data obtained ...

Coordination and harmony between different departments of a company can be an important factor in achieving competitive advantage if the company corrects alignment between strategies of different departments. This paper presents an integrated decision model based on recent advances of geometric programming technique. The demand of a product considers as a power function of factors such as produ...

growth of the petrochemical industry and its products has been followed growth in other sectors of production, use and trade of chemicals at national and regional levels. it is one of the basic industries which are feeder to other industry sectors as the engine of the economy and play a major role in developing countries. with no doubt mismanagement and improper use of chemicals lead to harmful...

This experiment was carried out for a period of 4 weeks with 240 day old straight- run broiler (Cobb-500) chicks to investigate the effects of administering electrolytes in drinking water on the productive performance (live weight, body weight gain, feed consumption, feed conversion and water consumption) and to determine the economic impact of using electrolytes. The chicks were randomly distr...

A heat exchanger network (HEN) for the process of methanol synthesis has been studied by combination of pinch design method and the application of “Twisted Tube” heat exchanger units as a new technology. The HEN is reconstructed based on the full utilization of maximum allowable pressure drops for the process hot and cold streams. An algorithm is developed to generate design procedure for twist...
