Modern Information Systems in Logistics Processes

Srećko ĆURČIĆ, Jelena PURENOVIĆ, Milan VESKOVIĆ

Today, many companies improve operating management processes, as a precondition for overall cost efficiency and as a key to ensuring competitive advantage. Therefore, companies pay special attention to the production logistics that can achieve a differential advantage in the market. The development of new information technologies is a very important area for efficient business management. Therefore, the logistics system should be developed as part of a single information system. The task of the logistics system is to ensure constant insight into the system’s condition, as well as directing to measures to improve and manage the work systems.

Optimizing Webpage Layout for Smartwatches – Avoiding Sticky Menus

Tanja KRUNIĆ, Petar VASILJEVIĆ

This paper is devoted to a problem that occurs in a novel discipline – web design for smartwatches. Smartwatches are devices with small screens, and therefore, designing a webpage for them is a challenge. In the process of adapting the page layout for smartwatches, many issues are the same as in mobile web design, since smartphones have small screens, too. But smartwatches have even smaller screen dimensions, so additional problems may occur in this case. Herein, we will consider one of such problems – the display of sticky navigation menus on smartwatches.

Analysis of Geometric Product Specifications Obtained by Different 3D Printing Strategies

The possibility of realizing prototypes of design solutions with minimal funds has made Fused Deposition Modeling the most popular technique of additive production. Workpieces created by this method of 3D printing can have significant deviations from the specification. Deviations from the ideal dimensions and shapes of geometric primitives occur due to inadequately chosen printing strategy, which includes, among other things, parameters such as nozzle/heated bed temperature, print speed, and infill percentage. In this paper, with the help of a coordinate measuring machine and a 3D scanner, the analysis of the influence of the infill percentage of workpieces on the deviations of quality characteristics from the ideal geometry in the form of CAD models was performed. Data processing showed that the workpiece with a lower infill percentage has smaller deviations from the specification than the workpiece with 100% infill (solid part).

One Solution for Smart Production and Processing of Food Products

This paper proposes a conceptual solution for the smart production and processing of food products. Smart factories are the basis of the proposed concept. This proposed solution enables factories to produce and process food products to optimize production based on feedback from end users to reduce food losses. Reducing food losses would indirectly reduce resources and energy losses and air, soil, and water pollution.
