- ItemEfficient Order Picking in a Warehouse with Double Demand Seasonality(Technická Univerzita v Liberci, ) Andar, Jakub; Dyntar, Jakub; Ekonomická fakultaIn this paper we highlight the advantages of adopting a broad simulation model of material flows as a useful foundation for developing system support for warehouse procedures that use WMS. The warehouse under consideration has a rectangular shape with parallel lanes and operates in two distinct seasons, necessitating different storage methods. The modified simulation model incorporates several strategies to enhance efficiency. Firstly, the S-shape routing technique is employed to optimize the movement of order pickers within the warehouse, minimizing travel time and increasing productivity. Additionally, a return technique is integrated to minimize empty travel distance, further reducing operational costs. Storage assignment within the warehouse is determined based on the frequency of item occurrence and the required storage technology. To establish an effective layout for each season, the study examines historical demand data and utilizes ABC analysis to classify goods. This dual layout design approach accounts for the unique demand patterns of each season, enabling the warehouse to maximize storage capacity and minimize operational bottlenecks. By considering elements such as seasonal demand, storage technologies, labor routing, and product classification, this research provides valuable insights for improving order picking efficiency, reducing costs, and enhancing customer service in seasonal warehouses. Implementing the proposed simulation-based technique can empower businesses to optimize their operations and thrive amidst changing market conditions, ultimately leading to increased profitability and customer satisfaction.
- ItemHospodářské trestné činy - právní a ekonomické aspektyAndar, Jakub; Karhanová Horynová Eva, JUDr. : 56827; Laboutková Šárka, doc. Ing. Ph.D. Skolitel : 57210; Severa Karel, Mgr. Konzultant : 54963; Čeňková Jitka, Ing. Konzultant2 : 57847Tato bakalářská práce se zabývá problematikou hospodářských trestných činů, zejména jejich právními a ekonomickými aspekty v oblasti dopadu na hospodářství.Cílem této práce je popsat a zhodnotit současnou právní úpravu těchto trestných činů, zejména s odkazem na zákon č. 40/2009 Sb., trestní zákoník v úplném znění a zákon č. 418/2011 Sb., o trestní odpovědnosti právnických osob a řízení proti nim.Práce se dále věnuje analýze takového škodlivého jednání v oblasti ekonomiky. Snahou je zhodnotit jak dopad veškerých forem hospodářské kriminality, tak dopad konkrétní vybrané skupiny trestných činů, a to zkrácení daně, poplatku a podobné povinné platby, ve formě karuselových podvodů. V práci je provedený také rozbor možností, které vedou k zamezení uvedené ilegální činnosti, jako například mechanismus přenesení daňové povinnosti, kontrolní hlášení DPH a elektronická evidence tržeb.
- ItemNavigating urban logistics challenges: An optimized approach to parcel distribution in the Prague city center(2024-02-28) Andar, Jakub; Huskova, Katerina; Dyntar, JakubIn this paper, we focus on metropolitan transport logistics that has always been difficult due to the need to transport goods through a complex urban infrastructure, heavy traffic, and dense populations. The goal of this paper is to describe a micro hub location in the neighborhood of the historic center of the city of Prague, the Czech Republic in a situation where the municipalities consider prohibiting the entry of trucks with combustion engines that currently provide cargo transportation for B2B partners operating in this area. Micro hubs represent the efficient last mile consolidation and distribution facilities located in or near urban neighborhoods and serving a spatially limited, densely populated delivery area. We propose a solution combining facility location problem, vehicle routing problem and balancing with the horizontal and vertical cooperation in supply chains to locate the micro hub in the area with extremely low availability of suitable space while respecting the necessity to connect this facility to an existing network of regional terminals operated by 3PLs to ensure the distribution of cargo across the board according to the requirements of customers. For the collection and distribution of parcels within the area, we suggest to use of cargo bikes and electric vans to provide environmentally sustainable service and minimize the harmful consequences of excessive traffic for residents. We also discuss the economic implications of adopting such innovative sustainable supply chain solutions for involved horizontal and vertical supply chain partners emphasizing different motivation aspects to convince these partners to cooperate and share scarce resources.
