“…e redesign of postal networks has been the object of attention in recent years. Mathematical models were developed to analyze cost efficiency [17] and optimize network replanning decisions, i.e., postbox locations [1,2]. e urban post office relocation problem was modeled byŠarac et al [18] who used a set covering location problem (SCLP) to determine the minimum number of permanent post offices required for providing a certain level of service.…”

Due to recent technological advancements, more diversified customer demand, and increasingly harder competition, traditional postal service systems have experienced significant changes all over the world. In Norway, through a strategic reform called post-in-shop, undertaken in 2013, most postal services are now provided at postal service counters located in retailer stores in order to improve accessibility, operational efficiency, and cost-effectiveness. This has led to a complex decision-making problem for the redesign of urban postal service networks across the country. In this paper, a two-stage method is proposed to solve a real-world urban postal service network redesign problem. First, two location models are employed to determine the optimal locations of postal service counters. In the second stage, a simulation model is built to evaluate the urban postal service system with different location and demand allocation plans under a realistic and stochastic environment. Among other insights, our results show that the proposed two-stage method can be used to effectively improve the accessibility of postal service networks by making optimal location-allocation decisions.

“…Cost Efficiency) (CE) jedinica poštanske mreže. Kao što je to utvrđeno u radu [7], razumevanje troškovne efikasnosti je od suštinskog značaja za razmatranje promena gustine dostavnih i isporučnih jedinica kod alternativnog scenarija. Da bi se donela odluka u vezi sa ovim promenama, potrebno je izvršiti analizu troškovne efikasnosti svake jedinice mreže.…”

This paper presents a potential solution to the issue of redefining the postal network, for the needs of an alternative reference scenario, using the DEA method. The authors use an integrated approach to analyze the cost efficiency of the postal network, which implies a separate consideration of the cost efficiency of delivery and non-delivery units of the network. The results obtained by combining the DEA method and the integrated approach can be useful for setting up and validating alternative scenario hypotheses, resulting in a redefined postal network.

“…da li su oni prouzrokovani neefikasnim radom ili nekonkurentnim uslovima rada ili sa oba. Ovakav pristup analize DMU bio je primenjen u radovima [14,15,16]. Na primer, u radu [14], na posmatranom uzorku imenovanih poštanskih operatora (IPO kao DMU) iz zemalja članica EU i Srbije, utvrđeno je za 2011. godinu da IPO iz Austrije, Slovenije i Španije rade unutar MPSS (CCR = BCC = 1), dok su IPO iz Nemačke, Velike Britanije, Grčke i Malte bili blizu da postignu MPSS status.…”

“…Naime, osnovna pretpostavka u studijama koje ispituju vezu između ljudskog kapitala i učinka je da znanje, veštine i sposobnosti zaposlenih imaju direktan uticaj na rezultate rada -povećanje nivoa znanja, veština i sposobnosti ima pozitivan uticaj na učinak i efikasnost, i obrnuto [17]. Što se tiče uticaja okruženja unutar kojeg DMU radi, u radovima [15,16], na primeru dostavnih jedinica poštanske mreže, pokazano je da lokacija dostavne jedinice ima veliki uticaj na troškovnu neefikasnost -pronađeno je da na troškovnu efikasnost utiču u većoj meri uslovi okruženja nego radna efikasnost.…”

A radial measurement o f efficiency on a selected numerical example involving multiple decision units (DMUs) is presented in this paper. Original CCR and extended BCC radial DEA models are used for this purpose. It is demonstrated here that DMUs can be efficient or inefficient in the use o f resources in achieving work results. The results o f the efficiency measurement indicate that the evaluation by the CCR DEA model is more strict compared to the BCC DEA model for each inefficient DMU regardless o f whether the efficiency measurement focuses on inputs or outputs.
