The job satisfaction of detectives investigating economic crime in the police directorates of Ljubljana-Maribor and some reasons for their fluctuation
Vinko Gorenak, Božidar John Željko, 2008, izvirni znanstveni članek

Opis: An average person spends almost a third of his life at work. It is therefore very important that the person is satisfied with their job. We could define job satisfaction as a factor with an important influence on increased quality in both professional and private life. The dissatisfaction of employees with their jobs is usually followed by fluctuation. This can be very damaging to an organization since employees are one of the most important resources. This article presents the results of various surveys on the satisfaction of police officers and detectives with their work, on fluctuation as a phenomenon and some of the reasons for it. In the empirical part of this article, the authors present a study done among the economic crime detectives working in the police directorates of Ljubljana and Maribor. The study showed that economic crime detectives are somewhat satisfied with their work but are still willing to change their jobs and leave the police for a better salary. The main factor for dissatisfaction is the low pay for their performance.

Assessing the impact of prices fluctuation on demand distortion within a multi-echelon supply chain
Francisco Campuzano Bolarín, Antonio Guillamón Frutos, Andrej Lisec, 2011, pregledni znanstveni članek

Opis: Price fluctuation is a practice commonly used by companies to stimulate demand and a main cause of the Bullwhip effect. Assuming a staggered step demand pattern that responds elastically to retailer’s price fluctuation, and by using a supply chain management dynamic model, we will analyse the impact of these fluctuations on the variability of the orders placed along a traditional multilevel supply chain. Subsequently, the results obtained will serve to propose a forecasting model enabling to calculate the potential variability of orders placed by each echelon on the basis of the price pattern used. Finally, under the hypothesis of an environment of collaboration between the different members of the chain, we propose a predictive model that makes it possible to quantify the distortion of the orders generated by each level.

Bullwhip effect problem in supply chains
Borut Buchmeister, Jože Pavlinjek, Iztok Palčič, Andrej Polajnar, 2008, izvirni znanstveni članek

Opis: In Supply Chain Management, a phenomenon called the "Bullwhip Effect" has attracted considerable attention. Overall supply chain evaluation needs to include the Bullwhip Effect. The Bullwhip Effect shows how small changes at the demand end of a supply chain are progressively amplified for operations further back in the chain. It is understood that demand forecast variance contributes to that effect in the chain. With this understanding, the authorsexperimented with two cases: stable demand with a single 5 % change in demand, and changing demand in periodic 10 % increases and later in the same decreases. Two stock keeping policies for all stages in the chain have been studied: to keep in stock i) one, and ü) two periods' demand. Results are shown in tables and charts. Increasing variability of production orders and stocks up the supply chain is evident. The effect indicates a lack of synchronization among supply chain members because of corrupt key information about actual demand. When we understand the nature of supply chain dynamics, there are several actions concerned with coordinating the activities of the operations in the chain, which is discussed in the last part of the paper.
