Although integrated process planning and scheduling (IPPS) problem is studied extensively as with due-date assignment (SWDDA) in the literature, there are only a few studies on integration of these three manufacturing functions which planning, scheduling, assignment. Since outputs upper stream effect downstream higher gives better global performance, it to integrate functions. In this study ear...

One of the key applications of operational research in health systems management is to improve the mechanism of resource allocation and program planning in order to increase the system efficiency. This study seeks to offer an innovative method for the planning and scheduling of health service units with the aim of reducing the patients' Length of Stay (LOS) in the Cardiac Surgery Ward of Razavi...

Research Question: The Last Planner System (LPS) and Location-Based Management System (LBMS) both aim to achieve the lean goals of decreasing waste, increasing productivity and decreasing variability. Q1: How to best link these two systems together to achieve better project performance? Q2: can the LBMS control mechanisms be integrated with LPS? Q3: Can phase pull scheduling be integrated with ...

Automated planning and scheduling, including automated path planning, has been integrated with an Internet-based distributed operations system for planetary rover operations. The resulting prototype system enables faster generation of valid rover command sequences by a distributed planetary rover operations team. The Web Interface for Telescience (WITS) provides Internet-based distributed colla...

Aircraft maintenance planning and scheduling constitute planning, control and execution of materials (spare parts), operations (inspection, disassembly and assembly activities) and resources (labour, machines, transport equipment, etc.). This is a complex problem due to large number of components involved at various planning and execution levels, and the size/nature of resource-intensive mainte...

in this paper, a multi-period and multi-resource operating room (or) scheduling and rescheduling problem with elective and semi-elective (semi-urgent) patients is addressed. a scheduling-rescheduling framework based on the so-called rolling horizon approach is proposed to solve the problem. the core of the proposed framework is a novel proposed mixed-integer linear programming (milp) model with...

Daewoo Shipbuilding Company, one of the largest shipbuilders in the world, had difficulties with planning and scheduling its production process. To solve the problems, Korea Advanced Institute of Science and Technology (KAIST) and Daewoo have been jointly performing the DAS (DAewoo Shipbuilding Scheduling) Project for three years from 1991 to 1993. To develop the integrated scheduling systems, ...

Resource constrained project scheduling problem (RCPSP) is mainly investigated with the objective of either minimizing project makespan or maximizing project net present value. However, when material planning plays a key role in a project, the existing models cannot help determining material ordering plans to minimize material costs. In this paper, the RCPSP incorporated with the material order...
