This paper considers the differentiation of each new product development program as multiple categories. Each R&D category involves redesigning/upgrading a specific current product. Each project has multiple choices of quality/technology standards. This work propose an approach to treat the multi-category and multi-standard project selection problem in which the scheduling is also considered concurrently under constrained periodically budget. The proposed approach consists of following four components: (1) selecting a project advancement strategy to serve as a scheduling framework for taking into account soft factors in scheduling process, (2) employing the brand-image score of consumers as the objective function for ultimately increasing long-run average profitability, (3) formulating a computable model in which periodical budget constraints are involved and ambiguous value-based time limits are specified, and (4) transforming the objective function into an appropriate form in which the parameters can be estimated more easily and the objective value can be predicated as a clear managerial implication. |
