摘要
Working time flexibility is of major concern to companies, and must be established by reaching arrangements with workers. Comparing flexibility arrangements is far from easy. Measures of flexibility that assume a probability distribution Of future demand are not really measuring flexibility, but rather risk. We define a space of states made up of possible working hours over several periods, and apply three measures of flexibility to it: the proportion of feasible states, the average cost and a new entropy-based measure of flexibility (EMF). The EMF is based on Shannon's entropy. We propose the use of three measures simultaneously for comparing the flexibility provided by a working time arrangement. Two examples are given: one that assesses the flexibility generated by using time accounts and overtime in a working time accounts (WTAs) modality, and one that compares the WTAs and hiring and firing (H&F) modalities.
