This study considers the shift minimization personnel task scheduling problem, which is to assign a set of tasks with fixed start and finish times to a minimum number of workers from a heterogeneous workforce. An effective lower bounding procedure based on solving a new integer programming model of the problem is proposed for the problem. An extensive computational study on benchmark data sets reveals that the proposed lower bounding procedure outperforms those existing in the literature and consistently and rapidly yields high quality lower bounds that are necessary for the decision makers to assess the quality of the obtained schedules.

Bu çalışmada,
başlangıç ve bitiş zamanları belli olan bir grup görevin, türdeş olmayan bir
işgücünden en az sayıdaki çalışana atandığı bir vardiya enküçükleyen personel
görev çizelgelemesi problemi ele alınmıştır. Bu problem için, problemin yeni
bir tamsayılı programlama modelini çözmeye dayalı etkin bir alt sınır yöntemi
önerilmiştir. Sayısal sonuçlar, önerilen modelin, literatürde varolan
yöntemlerden daha üstün olduğunu ve karar vericilerin elde edilen çizelgelerin
kalitelerini değerlendirebilmeleri için gerekli olan yüksek kaliteli alt
sınırları tutarlı ve hızlı bir şekilde verdiğini göstermektedir.
