Models of choice in concurrent-chains schedules are derived from melioration, generalized matching, and optimization. The resulting models are compared with those based on Fantino's (1969, 1981) delay-reduction hypothesis. It is found that all models involve the delay reduction factors (T - t2L) and (T - t2R), where T is the expected time to primary reinforcement and t2L, t2R are the durations of the terminal links. In particular, in the case of equal initial links, the model derived from melioration coincides with Fantino's original model for full (reliable) reinforcement and with the model proposed by Spetch and Dunn (1987) for percentage (unreliable) reinforcement. In the general case of unequal initial links, the model derived from melioration differs from the revised model advanced by Squires and Fantino (1971) only in the factors affecting the delay-reduction terms (T - t2L) and (T - t2R). The models of choice obtained by minimizing the expected time to reinforcement depend on the type of feedback functions used. In particular, if power feedback functions are used, the optimization model coincides with that obtained from melioration.
并发链程序中的选择模型源自改善、广义匹配和优化。将所得模型与基于法蒂诺（1969年，1981年）延迟减少假设的模型进行比较。研究发现，所有模型都涉及延迟减少因素（T - t2L）和（T - t2R），其中T是获得初次强化的预期时间，t2L、t2R是终端链节的持续时间。特别地，在初始链节相等的情况下，源自改善的模型与法蒂诺针对完全（可靠）强化的原始模型一致，并且与斯佩奇和邓恩（1987年）针对百分比（不可靠）强化提出的模型一致。在初始链节不相等的一般情况下，源自改善的模型与斯奎尔斯和法蒂诺（1971年）提出的修正模型的不同之处仅在于影响延迟减少项（T - t2L）和（T - t2R）的因素。通过最小化获得强化的预期时间得到的选择模型取决于所使用的反馈函数类型。特别地，如果使用幂反馈函数，优化模型与从改善中获得的模型一致。
