This paper proposes and evaluates a model of supply chains as networks of auctions. In this model, companies are represented according to the first level of the Supply Chain Council’s SCOR model and the trading strategy of the agents is adapted from a model proposed by Steiglitz and colleagues. Specifically, the highest level of SCOR treats a company as comprising three functions, namely Source...

Justified communication equilibrium (JCE) is an refinement for signaling games with cheap-talk communication. A strategy profile must be a JCE to stable outcome of nonequilibrium learning when receivers are initially trusting and senders play many more times than receivers. In the model, counterfactual “speeches” that have been informally used motivate past refinements messages actually sent. S...

Terms used in search queries often have multiple meanings and usages. Consequently, search results corresponding to different meanings or usages may be retrieved, making identifying relevant results inconvenient and time-consuming. In this paper, we study the problem of grouping the search results based on the different meanings and usages of a query. We build on a previous work that identifies...

State-of-the-art relational and continuous algorithms alike have focused on producing optimal or near-optimal query plans by minimizing a single cost function. However, ensuring accurate yet real-time responses for stream processing applications necessitates that the system identifies qualified rather than optimal query plans with the former guaranteeing that their utilization of both the CPU a...

In a programming project, it is easy to lose track of which files need to be reprocessed or recompiled after a change is made in some part of the source. Make provides a simple mechanism for maintaining up-to-date versions of programs that result from many operations on a number of files. It is possible to tell Make the sequence of commands that create certain files, and the list of files that ...
