Maintaining product availability is one of the biggest challenges in retail business because it directly relates to lost sale and decrease in customer loyalty. A solution that ensures a more accurate prediction and eliminates costly stock-outs and wasteful overstocks is an automatic replenishment system. The goal of this paper is to measure the impact that the automatic replenishment system can have on product availability in retail business, especially when it comes to specific product and store related risk factors. A large quantitative study measured the performance of manual and automatic replenishment processes in a sample of 85 stores and 95 products of a major retail chain in Serbia. The study concluded that utilization of an automatic replenishment system can reduce stock-outs for the retail chains up to 60%. Specifically, when ordered through an automatic replenishment system, fast-selling products recorded 40% greater availability, products on promotion 48% higher availability, and products in a high-density retail stores 59% higher availability. The findings extend current understanding of automatic replenishment systems, and especially their performance related to high-risk retail conditions.

Male hidroelektrane (MHE) igraju važnu ulogu u evropskom tržištu energetike i infrastrukturnih investicija. One doprinose razvoju zelene energije i smanjenju korišćenja fosilnih goriva, ali takođe interaguju sa društvenim i okolnim blagostanjem društva. Pristup Logičkog Okvira sa Matricom Logičkog Okvira (PLO/MLO) je alat za projekt menadžment razvijen od strane međunarodnih finansijskih institucija (MFI) sa ciljem obezbeđivanja pouzdanosti i nadzora kompleksnih projekata i investicija koje uključuju više učesnika. Postojeći problemi održivosti koji proizlaze iz MHE projekata širom Evrope su uzrokovani nedovoljno dobrom pripremom projekata MHE. Cilj ovog rada jeste da pokaže da korišćenje PLO/MLO obezbeđuje održivost i trajnu vrednost projekta tokom celog životnog ciklusa projekta MHE. Rad procenjuje ključne rizike razvoje i menadžmenta projekata MHE, vodeći nazad skroz do faza procene učesnika i definisanja cilja projekta. Rezultati rada pokazuju primere MHE projekata u Srbiji koji su razvijeni uz pomoć PLO/MLO u nekim fazama svog projektnog životnog ciklusa, poredeći ih sa onima koji su razvijeni bez korišćenja PLO/MLO u svom projektnom životnom ciklusu. Zatim se pokazuje na koji način PLO/MLO pomaže izbegavanju ovih rizika u budućem razvoju i menadžmentu MHE projekata. Konačno, on zagovara ekstenzivnu primenu PLO/MLO od strane investitora u buduće MHE projekate, naglašavajuči ključne prednosti korišćenja PLO/MLO tokom celog životnog ciklusa MHE projekta.

Research Question: This paper investigates whether the Monte Carlo simulation can be widely used as a practicable method for the analysis of the risks that impact project duration. Motivation: The main goal was to explore the use of the Monte Carlo simulation for project time management, and shed some light on the key benefits and drawbacks of this method. The paper reviewed the existing literature considering traditional use of the Monte Carlo for quantitative project risk analysis (such as Kwak & Ingall, 2007; Hulett, 2017) and elaborated the issue by suggesting potential improvements in terms of method modification for schedule management, such as event chain methodology proposed by Agarwal & Virine (2017). Another goal was to examine the capability of user-friendly software to provide project managers with some of these benefits. Idea: The core idea of this paper was to evaluate the value of the Monte Carlo method for project time and schedule management, by matching traditional foundations with modern techniques. Data: The paper used the secondary data extracted from relevant literature and project examples. A literature review reveals how the application of the Monte Carlo simulation evolved as a project management tool, along with specific benefits and concerns for its application. Tools: A detailed application of the Monte Carlo in predicting project duration is provided, and the applicability and viability of the method are proven through a case demonstration. Following the presentation of a practical example and discussion of the main features, some limitations and potential improvements to the Monte Carlo method are suggested. Findings: Even with the existence of certain limitations, the Monte Carlo simulation remains the primary method for quantitative analysis of project risks. Despite the Monte Carlo having been found to be applicable, adaptable and predictive of total project duration, it is found to be insufficiently used by practitioners. Contribution: The paper urges the need for research on successful diffusion of the Monte Carlo simulation and helps practitioners to understand the adaptability of the Monte Carlo simulation as a tool for risk quantification and its use for effective duration planning of their projects.

The application of earned value based metrics in Serbia lags significantly behind other developed economies, regardless of the fact that is has proven to be a very useful and flexible tool for prediction of total cost and time of construction projects. This paper aims to contribute to the wider use of earned value management (EVM) as a practical metrics that can be used to track performance of small-scale construction projects. Literature review reveals how the method evolved as a fundamental tool for construction projects monitoring and refers to specific issues concerning its implementation. In order to enable practitioners to realize all advantages of earned value based performance monitoring of small-scale construction projects, the applicability of such methodology is demonstrated through a case study.
