Fiyat Düzenlemeli Hizmet Firmalarında Optimum Sermaye ve İşgücü Yatırımı

Öz

Fiyatı devletçe veya belediyelerce belirlenmiş ve değişken talebin mutlaka karşılanması gereken şirketlerin optimal yatırım planları Optimal Kontrol tekniği kullanılarak incelenmiştir. Servisin üretim fonksiyonunun bir Cobb-Doulas tipi olduğu varsayılmıştır. Sabit Elastikiyetli İkame tipi üretim foknsiyonu da incelemede kullanılmıştır. Ancak sonuçların mahiyeti değişmemiştir. Üretim faktörlerinin ikisi de (İş gücü ve makina) yarı sabit varsayılmıştır. Talebin değişim oranı, işçilerin işten ayrılma veya emeklilik oranı ve makinaların eskime oranları sonucu belirleyen ana parametrelerdir. Her iki faktöre de yatırımın sıfır olduğu, makinalara yatırımın sıfır olduğu, iş gücüne yatırımın sıfır olduğu zaman dilimlerinin başlangıç ve bitiş zamanları belirlenmiştir. Bu sonuç şirketlerin tamir bakım ve insan kaynakları yönetim planlamasının daha iyi yapılmasına katkıda bulunacaktır.

Optimal Capital and Labor Investment in Price Regulated Service Firms

Öz

Optimal investment behavior of a price regulated service firm facing a fluctuating demand curve is studied using Optimal Control Theory. The firm is required to meet the demand at all times. Cobb-Douglas type of demand function is utilized in the analysis where both labor and capital are assumed to be quasi-fixed factors of production. Constant Elasticity of Substitution type of production function is also used in the analysis resulting in similar results. The rates of change of demand, attrition rate of labor, and the depreciation rate of capital are the primary factors determining the optimal behavior. The switching times between periods when investment in both factors is zero, when investment in capital is zero, and when investment in labor is zero are determined allowing better planning of maintenance periods of machinery and vacation planning.
