Secure Supply Chain Collaborations Project

One of the major sources of inefficiency in supply-chain management is information asymmetry; i.e., information that is available to one or more organizations in the chain (e.g., manufacturer, retailer) is not available to others. Information asymmetry is known to create inefficiencies in managing supply chains, among them under-investment in capacity, leading to shortages, misallocation of inventory, transportation, increased prices, and reduced customer service. It can also lead to increased use of premium shipping, increased penalties resulting from line shut-downs, and lost future business contracts. There are several causes of information asymmetry, among them fear that a powerful buyer or supplier will take advantage of private information, that information will leak to a competitor, fear of potential espionage of combined data sets, etc.

The goal of this project is to create techniques and tools that will enable supply-chain partners to cooperatively achieve desired system-wide goals without revealing the private information of any of the parties, even though the jointly-computed decisions require the information of all the parties. Such collaboration technologies have the potential to profoundly impact supply-chain management practice; and, by removing one major inefficiency therein, improve productivity and stimulate economic growth.
