摘要

This rejoinder responds to the commentary by van der Linden and Li entiled “Comment on Three-Element Item Selection Procedures for Multiple Forms Assembly: An Item Matching Approach” on the article “Three-Element Item Selection Procedures for Multiple Forms Assembly: An Item Matching Approach” by Chen. Van der Linden and Li made a strong statement calling for the cessation of test assembly heuristics development, and instead encouraged embracing mixed integer programming (MIP). This article points out the nondeterministic polynomial (NP)–hard nature of MIP problems and how solutions found using heuristics could be useful in an MIP context. Although van der Linden and Li provided several practical examples of test assembly supporting their view, the examples ignore the cases in which a slight change of constraints or item pool data might mean it would not be possible to obtain solutions as quickly as before. The article illustrates the use of heuristic solutions to improve both the performance of MIP solvers and the quality of solutions. Additional responses to the commentary by van der Linden and Li are included.
