“…The number of times that a planned order is rescheduled irrespectively of the planned quantity (Heisig, 1998). This case is directed to minimize disruptions in the production sequence, since this would imply extra setup time.…”

“…Now the worker's objection is considered. Assumption, when the mean of the production variable is mp, the effort and the energy which the worker pay for each output is a continuous convex function R ( m ) ; when the acceleration factor equal 8, the effort and the energy which the worker pay for each output is a continuous convex function V (8). According to the actual situation, R" ( m ) < 0, R"( m ) > 0, V' (8) …”

Abslract The incentive effects and dynamic aspects of the inventory system were discussed in this paper. The wage policy was regarded as a factor to influence workers' thinking of their action. A multiple objective problem was constructed for the owners and the workers. At the same time, the planning stability is considered in the presented model. Since the process speed is decided by the dynamic demand of production or the interior system itself, two situations were discussed in this paper.
“…Durieux et Pierreval (2003) indiquent que le terme stabilité est généralement mis en opposition à celui de nervosité. Stabilité et nervosité de la planification sont souvent traitées dans la littérature au niveau du calcul des besoins (MRP) (Yano et Carlson, 1987 ;Ho, 1989 ;Sridharan et Laforge, 1990 ;Jensen, 1993 ;Heisig, 1998). Calculer un programme directeur de production (PDP) revient à mettre en place un horizon glissant, ce qui implique de le recalculer avec une périodicité ∆ ; par conséquent, ce type de pratique induit des variations dans les quantités de production résultantes.…”

RESUME. Ce travail porte sur la planification tactique d'une chaîne logistique dans un environnement incertain et perturbé. Dans le but de minimiser l'effet des perturbations dues à ces incertitudes
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
