Bu
çalışmada, tüm saha hizmet operasyonlarında gözlemlenen, çoklu yetenek
gereksinimi içeren işgücü rotalama ve çizelgeleme problemi ele alınmıştır.
Problem, gerçek hayatta enerji dağıtım şirketlerinin günlük olarak karşılaştığı
bir planlama probleminden yola çıkılarak tanımlanmıştır. Amaç, farklı
konumları, öncelikleri ve yetenek gereksinimleri olan işler için; uygun
teknisyen ekiplerinin ve sıralı iş listelerinin optimal bir şekilde
belirlenmesidir. Öncelikle, problem için iki öncelikli amaç fonksiyonu bulunan
bir matematiksel model geliştirilmiştir. Problem boyutu büyüdükçe modelin kabul
edilebilir sürede ve kalitede çözüm vermemesi nedeniyle,  büyük ölçekli problemler için kısa sürede
kaliteli çözümler üreten, üç aşamalı bir sezgisel yöntem geliştirilmiştir.
Geliştirilen yöntemin etkinliği hem rastgele türetilmiş, hem de gerçekçi veri
kümeleri üzerinde gösterilmiştir.

Forming, Scheduling and Routing Field Service Teams for Multi-Skill Prioritized Tasks

Öz

In
this research, we study the multi-skill workforce scheduling and routing
problem that arises in all field service operations. The problem originates
from a daily planning problem faced by the electricity distribution companies.
Given a set of geographically dispersed tasks with different priorities and
skill requirements, and a set of technicians with different skills; the
objective is to form teams of technicians while assigning a sequence of tasks
to each team in an optimal manner. 
First, we develop a mathematical model that has two prioritized
objective functions for the problem. Since the solution time and quality of the
model degrades quickly as the problem size increases, we devise a three-phased
heuristic that generates good solutions efficiently for large-scale problems.
We demonstrate the performance of the heuristic through randomly generated and
realistic problem instances.
