This paper presents a method for scheduling resources in complex systems that integrate humans with diverse hardware and software components, and for studying the impact of resource schedules on system characteristics. The method uses discrete-event simulation and integer linear programming, and relies on detailed models of the system’s processes, specifications of the capabilities of the syste...

Multi-criteria scheduling optimization with genetic algorithms is described. Scheduling optimization methodology provides the planner with a quick and efficient scheduling method and enables him/her to experiment and decide which of the suitable solutions will become the production plan. The scheduling system is composed of a business information system a database, a discrete event simulation m...

the multi-criteria decision making model is an important tool for decision making in water resource management. in this paper, the topsis model was used to rank seven flood management options in the gorganrood river flood management project, including conservation of natural condition, golestan reservoir management, levee construction, diversions-channel construction, flood forecasting and warn...

A novel labour-hour budgeting methodology is proposed by integrating productivity concepts in project scheduling and to enhance the accuracy of labour cost for planning labour-intensive projects. The applies discrete event simulation approach represent crew formation, resource utilization flowing between consecutive activities, which allows quantitatively characterizing impact semi-productive t...

Holonic enterprises are considered as one of the new types of networking organizations used to increase business efficiency. But in practice it requires to introduce a new type of management stimulating the interpreneur approach, active interaction between actors within the project teams, coordinated and effective decisions on resource scheduling in case of unpredictable events (new projects, b...

Parallel processing is the key to fulfill the high demands on computational resources in scientific computing. This has further pushed researches in High Performance Computing into the mainstream. Numerous powerful computer systems are then born. Especially, low-cost powerful clusters, which are set up by connecting many personal computers/workstations in a high speed network, were developed ra...

Railway scheduling is a complex task of rail operators that involves the generation of a conflict-free train timetable. This paper presents a discrete-event simulation-based optimization approach for solving the train timetabling problem to minimize total weighted unplanned stop time in a hybrid single and double track railway networks. The designed simulation model is used as a platform for ge...

Agile, fast and flexible production networks are a must in today’s global competition. The interrelations between manufacturing systems and processes are becoming more complex and the amount of data for decision making is growing. Manufacturing, engineering and production management decisions involve the consideration of multiple parameters. These often complex, interdependent factors and varia...

Advance Reservations are an important concept to support QoS and Workflow Scheduling in Grid environments. However, the impact of reservations from the Grid on the performance of local schedulers is not yet known. Using discrete event simulations we evaluate the impact of reservations on planning-based resource management of standard batch jobs. Our simulations are based on a real trace from th...
