We investigate the sales and operations planning (S&OP) problem at Vestel Electronics, a major television manufacturer located in Turkey. The company’s product portfolio is very wide due to a large number of configuration options, and changes rapidly due to technological advances. Demand volatility is high and materials procurement requires long lead times. Hence, the S&OP process is critical f...

Because of today's strong competition, most manufacturing organizations continually try to increase their profits and reduce their costs. Accurate sales forecasting is certainly an inexpensive way to meet these goals because it leads to improved customer service, reduced lost sales and product returns, and more efficient production planning (Doganis et al., 2006). Forecasting future demand is c...

Industries conduct the Sales and Operations Planning (S&OP) to balance demand supply aligned business targets. This study aims at proposing a model an algorithm for tactical chain planning admitting uncertainty reflecting peculiar S&OP aspect of rolling horizon planning. Therefore, two-stage stochastic programming is developed solved via multi-cut Benders decomposition algorithm. The solution m...

Sales & Operations Planning (S&OP) activities are among the most important, but also the most complicated, tasks in supply chain management. And we need not dwell on the complexity--you all know too well the difficulties of running successful S&OP processes. But if you read the current articles on S&OP by supply chain software vendors, consultants and pundits, you will frequently find them reco...
