I am an Industrial & Mechanical engineer; with more than twenty years of experience as a production manager and production planner in leading companies in ISRAEL, I also worked as a CAD/CAM engineer, software developer and training manager. In addition to my experience, which includes the use of several software packages, I have extensive knowledge of the known approaches, like MRP,TOC, Lean (JIT) and rules of thumb (SPT, FCFS, EDD, FIFO etc.).During my work, I realized that the existing scheduling solutions are not enough to deal with the challenges of the dynamic environment of job shops, flow shops and assembly lines. It encouraged me to develop a new algorithm and software, which avoids their pitfalls, deals with the scheduling challenges and provides the best solutions for production planning and scheduling.The main advantage of the software is its ability to optimize production, shorten the total lead-time (Makespan) and hence increase the operating profit. The software is intended for plants characterized by producing multiple products in a process, which includes several steps in several work-centers.
