Sharing information is regarded as one of the most effective ways of improving supply chain performance. Benefiting from visibility requires the efficient use of real demand and market trend information and sharing it with your suppliers. However, to implement visibility in supply chains in practice in a manner that improves the performance of the supply chain i s challenging. The current state of visibility in the demand-supply network of an original equipment manufacturing company was studied. The project concentrated on the end-to-end view of demand information. The most relevant information from the various information sources was identified and tested in order to improve the performance of the supply chain. On the basis of the test results and a literature survey, five proposals on how to proceed in benefiting from visibility are presented.
Planning processes along a demand supply network in an environment characterized by rapid market fluctuations and product changes are studied. The relationship between demand planning and the bullwhip effect is investigated by comparing planning accuracy in different demand supply network echelons and locating where there is most nervousness. The results show that planning accuracy varies between the parties in the supply chain. A proposal is made to stabilize planning in an environment characterized by fast market and product changes. Besides the increased complexity of the network the frequent changes in product portfolio makes the management of demand supply networks more challenging.
Purpose -The purpose of this article is to propose a planning process that takes into account that manufacturers of original equipment have products at different stages of the product-life cycle, and utilizes sales and inventory information collected from distributors and retailers. Design/methodology/approach -The research paper describes the construction and testing of a planning process. Findings -Trials in a case company indicate that supply chain responsiveness can be improved in product launches using the proposed process. Supply chain efficiency in the maturity phase can also be improved.Research limitations/implications -The usefulness and effectiveness of the proposed process depend on the assumption that product mix changes can be modeled and point-of-sales and channel sell-through data are available regularly and reliably. Practical implications -Modeling and monitoring the variant mix on the total market level can be used to improve supply chain responsiveness to mix changes in product launches. The introduction of this planning process reduces the need for planning in the sales units. Originality/value -The paper shows how the quality of variant forecasting for an original equipment manufacturer can be improved with access to channel visibility in the market introduction phase.
