Abstract
New production technologies like “just-in-time” production lead to special scheduling problems involving due dates d i . Contrary to classical scheduling problems where the objective function simply involves lateness L i = C i − d i or tardiness T i = max{0, C i − d i } penalties, earliness E i = max{0, d i − C i } is now also of importance. Objective functions such as Σ w i | L i | and Σ w i L i 2 are typical of “just-in-time” situations. Note that L i = T i + E i and L i 2 = T i 2 + E i 2. From the practical and theoretical point of view, situations in which all due dates are equal are of importance. This due date d may be a given parameter of the problem or it may be a variable, i.e. we are interested in an optimal due date d opt with respect to the objective function. To indicate these special situations we add d or d opt to the job characteristics of the problem. If the due date is a variable, then we may add due-date assignment costs w d · d to the objective function.
