On the Complexity of Broadcast Scheduling Problem
نویسندگان
چکیده
In this paper, a broadcast scheduling problem (BSP) in a time division multiple access (TDMA) ad hoc network is analyzed in terms of its computational complexity. In a TDMA frame, time is divided into equal length transmission slots. The objective of the considered version of BSP is to provide a collision free broadcast schedule which minimizes the total frame length. Wang & Ansari (1997) have observed that the recognition version of BSP is NP-complete, however, their proof of NP -completeness was incorrect. This paper proves that BSP is indeed NP-complete.

An algorithm for multi-objective job shop scheduling problem
Scheduling for job shop is very important in both fields of production management and combinatorial op-timization. However, it is quite difficult to achieve an optimal solution to this problem with traditional opti-mization approaches owing to the high computational complexity. The combination of several optimization criteria induces additional complexity and new problems. In this paper, we pro...

متن کاملBi-objective Optimization for Just in Time Scheduling: Application to the Two-Stage Assembly Flow Shop Problem
This paper considers a two-stage assembly flow shop problem (TAFSP) where m machines are in the first stage and an assembly machine is in the second stage. The objective is to minimize a weighted sum of earliness and tardiness time for n available jobs. JIT seeks to identify and eliminate waste components including over production, waiting time, transportation, inventory, movement and defective...
متن کاملMinimizing the Number of Tardy Jobs in the Single Machine Scheduling Problem under Bimodal Flexible and Periodic Availability Constraints
In single machine scheduling problems with availability constraints, machines are not available for one or more periods of time. In this paper, we consider a single machine scheduling problem with flexible and periodic availability constraints. In this problem, the maximum continuous working time for each machine increases in a stepwise manner with two different values allowed. Also, the durati...
