Electronics and Semiconductors

How semiconductor and electronics manufacturers are using optimization to improve efficiency and manage bottlenecks in manufacturing and supply chain processes

It is a critical time for the electronics and semiconductor industries. Economic volatility, cyclical demand, short product life cycles and highly complex supply chains are among the industry’s ongoing challenges. Add to that today’s delivery backlogs, supply chain disruptions and the slowness in bringing new production facilities online and manufacturers face tremendously consequential make-or-break decisions.

Decision support software systems that incorporate widely-used mathematical optimization and operations management methods present a relatively fast, flexible and low-cost way to tackle hard operational planning and scheduling decisions to ease production and supply chain bottlenecks and increase throughput in the short term. They are commonly used to support long-term/strategic planning decisions and mid-term tactical decisions.

These systems can be easily adapted to also accommodate future business changes so that planning and scheduling decisions can be made with a full view of all available situational data. This could include business objectives, supply and demand actuals and forecasts, resource constraints and any other considerations.

Packaged vs Custom Software Solutions

Packaged planning and scheduling systems rarely meet the needs of semiconductor and electronics manufacturers. For this reason, most manufacturers’ processes are still planned and scheduled either manually or with the help of custom-developed software systems. Packaged on-the-shelf systems tend to be very feature-limited and are hard to maintain or enhance. As a result, process inefficiencies are widespread.

Production Planning & Scheduling

Production planning and scheduling in semiconductor manufacturing is a good example of a use case that can bring tremendous efficiency improvements through optimization approaches because of its complexity. It can involve hundreds of steps and specific constraints such as reentrant flows, sequencing rules, suppliers’ constraints (capacity and lead times), different kinds of machines (parallel, batch, cluster), failures and preventive maintenance requirements. Optimization-based systems used advanced mathematical approaches running on high-performance computers to quickly sift through millions of possible solutions and present the ”best” according to the planner’s desired trade-off between the various objectives (such as balancing cost and service level).
