Time Determination

Optimal release time determination is a typical application of software reliability models. In this decision process, reliability and cost are the two important dimensions that are generally considered. Most existing research formulates this decision process as single-objective optimization problems. Although these formulations can greatly reduce the complexity, they can hardly reflect the nature of the decision process, which is essentially a multi-objective optimization problem. More specifically, maximizing reliability and minimizing cost should be achieved simultaneously. Due to this consideration, in this paper, software release time determination is investigated by various multi-objective optimization approaches, including the trade-off analysis, multi-attribute utility theory, and physical programming approach. Numerical examples are provided for illustrative purpose. The applicability and limitations of different multi-objective optimization approaches are also discussed, which can help management to make a more reasonable decision in practice.

Sequential Trial

Left/right “fixed” responses to arrow targets are influenced by whether a masked arrow prime is congruent or incongruent with the required target response. Left/right “free-choice” responses on trials with ambiguous targets that are mixed among fixed trials are also influenced by masked arrow primes. We show that the magnitude of masked priming of both fixed and free-choice responses is greater when the proportion of fixed trials with congruent primes is .8 rather than .2. Unconscious manipulation of context can thus influence both fixed and free choices. Sequential trial analyses revealed that these effects of the overall prime context on fixed and free-choice priming can be modulated by the local context (i.e., the nature of the previous trial). Our results support accounts of masked priming that posit a memory-recruitment, activation, or decision process that is sensitive to aspects of both the local and global context.
