Supply chain is all about collaboration for managing the product demand smoothly. The supply chain planning becomes complex as the number of products (and thus partners) grows. Most of the difficulty in planning arises from the uncertainties in demand and supply. To manage the supply chain smoothly, one option is to limit the number of products but businesses offer a portfolio of products to cater a large pool of customers. In this situation, to keep the supply chain lean, products are designed in such a way that most of the final products share several common or economically substitutable components / intermediate products and processes. There are two extremes: Designing the product specific component for each product; and designing a single universal component that can fit in every product. Both options come with certain advantages and disadvantages and to balance the advantages and disadvantages associated with the both, final products are segregated into different categories with each category sharing substitutable components. For instance, a paper roll of a specific width can be used to produce multiple final products of varied width. Determining the number of categories and classification of products into categories are very complex problems. In mathematical terms, the problem is known as set partition problem and in practice it is called assortment problem. In supply chains we encounter numerous assortment type problems at various stages (warehouse, sourcing, retail, transportation, etc.). Due to combinatorial and nonlinear nature of these problems efficient solution approaches are required. In this research, our first step is to do systematic review of the relevant literature and enrich the existing knowledge. We have identified few assortment problems associated with supply chains and in the second step we will develop mathematical modeling based approaches and theory to solve such problems. Based on the problem complexity, problem size and usage we will develop and test combination of approaches. Thirdly, the most effective and suitable approaches will be disseminated through publications and seminars. In particular, our key focus is to: 1) Develop and test strategies which are more suitable for supply chains under these circumstances. 2) Develop mathematical programming solution approaches which are effective and efficient in solving such complex models. 3) Develop /explore test cases for bench-marking the performance. The outcome of this research will be a set of methodologies and planning tools that could be used by researchers as well as practitioner. Other outcomes of the research include several highly qualified professionals trained in this area of research.

供应链是关于协作，以顺利管理产品需求。随着产品（以及合作伙伴）数量的增加，供应链规划变得复杂。规划的大部分困难来自于需求和供应的不确定性。为了顺利管理供应链，一种选择是限制产品数量，但企业提供产品组合以满足大量客户的需求。在这种情况下，为了保持供应链的精益，产品被设计成这样一种方式，即大多数最终产品共享几个共同的或经济上可替代的组件/中间产品和过程。有两个极端：为每个产品设计特定于产品的组件；并设计一个单一的通用组件，可以适用于每一个产品。这两种选择都有一定的优点和缺点，为了平衡两者的优点和缺点，最终产品被分成不同的类别，每个类别共享可替代的组件。例如，一个特定宽度的纸卷可以用来生产多种不同宽度的最终产品。
