| Abstract | Inventory replenishment practices play significant role in supply chain networks and they are strongly associated with overall supply chain performance. This paper presents a state-space model of a stochastic series multi-node supply chain, controlled via local proportional-integral inventory replenishment policies. The model is triggered by identically distributed and uncorrelated random variables which represent uncertain customer demand. The proposed model is analyzed under stationarity, provided that control parameters belong to a certain range which is clearly specified. Simple recursive techniques are developed to calculate explicitly the associated covariance matrix in closed parametric form. This allows to analyze the effect of control parameters in the inventory practices on the bullwhip effect. It is shown that proportional-integral replenishment practices can be applied to explain in qualitative terms the main performance and stability properties of supply chains. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
