Many real-world planning problems require sophisticated reasoning about numeric resources, including sharing of resources by different actions. Constraintbased planners offer machinery to represent complex constraints and dependencies between actions. However, such planners usually consider a single partial plan at a time, and limit themselves with finding a feasible solution. Alternatively, pl...

in iran the mainstreaming tool for integrating environmental concerns into energy sector is an energy-environment review (eer-iran). this paper comprises: (i) an analysis of the current situation with regards to energy production and consumption; (ii) an evaluation of the growth prospects with regard to energy production and consumption; (iii) the identification of environmental issues induced ...

Improvements in the agility of manufacturing systems in SMEs have promoted the emergence of collaborative engineering and production networks in which the partner companies cooperate to reach a shared objective. To date, much work has been undertaken to develop models and tools that facilitate hierarchical collaboration using concurrent engineering practices. In this paper a horizontal cooperat...

In a competitive market, semiconductor fabricator must face an environment with multi-product types, multi-priority orders and demand changes in time. Since semiconductor fabrication has a very complicated production process, the above-stated characteristics make the production planning even more difficult. This paper applies data envelopment analysis (DEA) to find a set of product family mix t...

The production planning problem, that is, to determine the production rate of a factory in the future, requires an aggregate model for the production flow through a factory. The canonical model is the clearing function model based on the assumption that the local production rate instantaneously adjusts to the one given by the equilibrium relationship between production rate (flux) and work in p...

BACKGROUND In 2009, the Safety Planning, Evaluation and Reporting Team gave detailed recommendations for a well-planned and systematic approach for safety data collection and analysis. Important aspects of this approach included regular reviews of aggregate data by a multidisciplinary team focusing on safety. PURPOSE This article provides information to facilitate the planning and implementat...

At present, iron and steel enterprise develops towards the direction with many procedure, many process, many variety and many specification, and reaches hundreds and thousands of product series and product mix, how to plan, organize and control steel production, production schedule of its product line are key issues. According to the main characteristics of production line of iron and steel ent...

This paper addresses the aggregate production planning problem with different operational constraints, including production capacity, workforce level, factory locations, machine utilization, storage space and other resource limitations. Three production plants in North America and one in China are considered simultaneously. A pre-emptive goal programming model is developed to maximize profit, m...
