The overall flow of the final test of integrated circuits can be represented by the job shop model with limited simultaneous multiple resources in which various product mixes, jobs recirculation, uncertain arrival of jobs, and unstable processing times complicate the problem. Rather than relying on domain experts, this study aims to develop a hybrid approach including a mathematical programming...

Projects are increasingly perceived as complex systems, yet little work has been done in developing methodologies that are theoretically grounded on complex systems theory. In response, this article argues the practical utility of a recently introduced model that draws on notions from Network Science (NS) – a prominent domain in the study of complexity. Its utility is exemplified in the context...

In most practical domains, scheduling is not a one-shot generative task of producing time and resource assignments for pre-specified sets of requirements and capabilities, but an iterative process of getting the constraints right. Initial solutions are developed (at some level of detail) to understand the feasibility of various requirements and the sufficiency of assumed resources. This require...

Abstract ‘Life is Bottled Sunshine’ is a fourword summary of the significance of photosynthesis for life on Earth. We all know the importance of the audio visual tools for communicating scientific principles to the students. Du...

Project planning and control are the essentials of project management. The first steps of the project planning require some knowledge of the concept of the product that the project is expected to deliver. The initial project plan, scope of work, Work Breakdown Structure, and allocation of resources rely on understanding of at least the top-level product functionality, architecture, and concept ...

We study scheduling problems on a machine of varying speed. Assuming a known speed function (given through an oracle) we ask for a cost-efficient scheduling solution. Our main result is a PTAS for minimizing the total weighted completion time on a machine of varying speed. This implies also a PTAS for the closely related problem of scheduling to minimize generalized global cost functions. The k...

This paper describes the evolution of a production planning system (PPS) from a simple work sequence generation tool to a useful, sustained scheduling system. Three stages of evolution are described. In the first stage, a Gantt chart sequencing tool was converted to a scheduler’s information system. This change was driven by the need to support the scheduler’s daily task. The second stage of ev...

The web has become the main platform for deploying business and social application and organizational information systems. Web Project management is relatively new field of knowledge, which has been dynamically developing. Goal of project management is providing solutions to existing problems, ranging from simple problems of preparing a wedding to setting up a factory or building a space ship. ...
