Robust Resource Investment Problem with Time-Dependent Resource Cost and Tardiness Penalty

A. Hattab, M. Haouari
2016 2016 IEEE International Conference on Industrial Engineering and Engineering Management (IEEM)  
The Resource Investment Problem (RIP) is a variant of the well-known Resource Constraint Project Scheduling Problem (RCPSP) that requires finding the optimal resource allocation, given a preset completion  ...  The practical relevance of RIP is very obvious; since the decision maker (the project manager for example) wants to know what resources are required to achieve the targeted project completion date.  ...  The same algorithm with some modification can be also used to solve other scheduling problems with different objective.  ...

Exploiting Immunological Properties for Ubiquitous Computing Systems [chapter]

Philipp H. Mohr, Nick Ryan, Jon Timmis
2004 Lecture Notes in Computer Science  
This paper argues that such properties are essential for the creation of future context-aware and ubiquitous systems where the need for such properties is becoming increasingly clear.  ...  To that end, we present an immune inspired system, which draws heavily on the immune network metaphor to create a metastable context-aware memory system that could be delivered in small hand-held devices  ...  Possible options are also represented by attribute vectors, one for each option (options may comprise of an arbitrary number of attributes).  ...
