We consider two single-machine group scheduling problems with deteriorating group setup and job processing times. That is, the job processing times and group setup times are linearly increasing or decreasing functions of their starting times. Jobs in each group have the same deteriorating rate. The objective of scheduling problems is to minimize the sum of completion times. We show that the sum...

1. Motivations for the Book Building systems that are trustful is one of the main challenges which software developers are facing. Dependability-related concerns have accompanied system developers since the first day these systems were built and deployed. Obviously various things have changed since then, including, the nature of faults and failures, the complexity of the systems, the services t...

A large number of choices exist when designing a reliable memory system. The choices range from simple replication to complex error control codes (ECC). Simple replication (without ECC) has a better performance as compared to systems using ECC, as ECC necessitate decoding, deteriorating the performance. Clearly, simple replication improves performance at the cost of increased redundancy. An int...
