“…Many researchers have studied the use of PERT/CPM techniques for BPM such as simulation for the execution, control and management, optimization methods to analyze the workflow system, to-be models, resource constraint-based process models and reduced process cycle time in terms of I4.0 process (e.g. Gunasekaran and Kobu, 2002;Rhee et al, 2004;Aytulun and Guneri, 2008;Ajiboye, 2011;Xie et al, 2013;Jim enez-Ram ırez et al, 2015;Erdei et al, 2018;Mustapha et al, 2018). Furthermore, studies on resource allocation and RCPSP in BPM have been conducted across a broad range of topics (e.g.…”

“…The CPM method was used for process cycle time without resource constraint in the process analysis stage. In the literature, the CPM method has been applied in BPM to focus on the calculation of cycle time for the process (Gunasekaran and Kobu, 2002;Ajiboye, 2011;Erdei et al, 2018;Mustapha et al, 2018). Therefore, this study focuses on calculating the cycle time of the process in the process analysis stage as the as-is model.…”

PurposeThe aim of this study is to provide a holistic analysis of all possible maritime business logistics processes related to import and export shipments in a fuzzy environment through a case study of a maritime logistics company based on the as-is and to-be models within business process management (BPM).Design/methodology/approachThe analyses considered the following perspectives: (i) in the stage of the process identification, the definition of the problem was carried out; (ii) in the stage of the process discovery, ocean department was divided into ocean export/import operation departments; ocean export/import operation were divided into freight collect/prepaid operation processes; ocean export/import logistics activity groups were broken down into sub-activities for freight collect/prepaid operation; the logistics activity groups and their sub-activities were defined; each sub-activity as either operation or documentation process group was classified; the durations of sub-activities were evaluated by decision-makers (DMs) as fuzzy sets (FSs); the monthly total jobs activities were estimated by DMs as FSs; the applied to monthly jobs activities of total shipments were estimated by DMs as FSs; the durations of each sub-activities were aggregated; the duration of the logistics activity groups and the sub-activities for per job were calculated; the cumulative workload of logistics activity groups and sub-activities were calculated; the duration of sub-activities for per job as operation or documentation departments were calculated, (iii) in the stage of the process analysis, cumulative ocean export/import workload as operation or documentation for freight collect/prepaid were calculated; duration of activity groups and sub-activities for per job as operation or documentation were calculated; cumulative workload activity groups and sub-activities as operation or documentation were calculated, (iv) in the stage of the process redesign, cumulative workload, process cycle time as operation and documentation group and required labor force were calculated; the process cycle time of the theoretical, the as-is model and the to-be model were calculated: (i) the theoretical minimum process cycle time without resource were calculated by the critical path method (CPM), (ii) the process cycle time of the as-is model perspective with the 1 person resource constraint and (iii) the process cycle time of the to-be model perspective with the 2-person resource constraint were calculated by the resource constrained project scheduling problem (RCPSP) method.FindingsThe methodology for analyzing the ocean department operation process was successfully implemented in a real-life case study. It is observed that the results of the to-be model can be applicable for the company. The BPM-proposed methodology is applicable for the maritime logistics industry in the present study; however, it can be applied to other companies in maritime logistics as well as other industries.Originality/valueThis study contributes to research using BPM methodology in maritime logistics. This is the first study the logistics process analyses were carried out in terms of including all operation processes for a company. All processes were analyzed by using BPM methodology in maritime logistics. This study demonstrated the application of the BPM as-is and to-be models to maritime logistics. The as-is and the to-be models of the BPM methodology were applied in maritime logistics.Research implicationsThis methodology applied in this study can enable organizations operating in the time-urgent maritime logistics sector to manage their logistics processes more efficiently, increase customer satisfaction, reduce the risks of customer loss due to poor operational performance and increase profits in the long term. Through the use of these methodologies utilizing FSs, the CPM and the RCPSP methods, this study is expected to make contributions to the BPM literature and provide original insights into the field. Furthermore, this study will undertake a comprehensive analysis of maritime logistics with respect to BPM to deliver noteworthy contributions to the maritime logistics literature and provide original perspectives into the field.

“…Przedsiębiorstwa rolnicze charakteryzują się kapitałochłonnością, niską rentownością, powolnym zwrotem kapitału i wysokim ryzykiem. Większość tych cech wynika z sezonowości produkcji rolnej (Erdei, Popp, Oláh, 2018). Należy pamiętać, że w analizach finansowych przedsiębiorstw rolnych dane bilansowe na koniec roku zazwyczaj nie odzwierciedlają faktycznego zarządzania przedsiębiorstwem rolnym i często są słabsze od danych na koniec roku (Gál, 2013).…”

“…Agricultural enterprises are specific in the following aspects: capital intensive, low profitability, slow return on capital, and high risk. Most of these characteristics result from the seasonality of agricultural production (Erdei, Popp, Oláh, 2018). In financial analyses of agricultural enterprises, it is important to bear in mind that the year-end balance sheet figures for agricultural enterprises do not usually reflect the actual management of the agricultural enterprise and are often worse than the year-end figures (Gál, 2013).…”

Subject and purpose of work: The paper examines two of the most important sectors of agriculture, crop and livestock production, in a time series analysis. The authors analyzed the number of enterprises, the number of employees, labor costs, turnover, and balance sheet total, and also assessed the evolution of liquidity and profitability in the two sectors, broken down by size. Materials and methods: The results of livestock and crop production were examined separately for the period 2008-2020. The analysis was based on aggregated data from the National Tax and Customs Administration in Hungary. Enterprises with the NACE REV 0140 for animal husbandry and 0110 for crop production were studied. In the research time series analysis and, where possible, trend analysis were performed. Results: In the research, the following indicators were examined using time series analysis in both crop and livestock production: the number of companies, the number of employees, the net sales revenue, the composition of net sales, the development of the balance sheet total, cost structure, labor costs, the quick ratio of liquidity, and the ROA indicator. Conclusions: Agricultural enterprises are most affected by the downward trend during the period under review, with the exception that the animal husbandry sector started to decline earlier than the crop production sector.

A termelésirányítási rendszerek ma informatikai aspektusokat is igényelnek, amikkel automatizálhatók, így könnyebben áttekinthetők a folyamatok. Kutatásom során három élelmiszergyártással foglalkozó vállalat 4 és fél évnyi adathalmazát és gépállományát elemeztem. Megállapítottam, hogy az ezen vállalatok a folyamatrendszerű gyártást részesítik előnyben. A késztermék előállításának egyes szakaszainak vizsgálatára az egyik legjobb időorientált módszert, a CPM elemzést alkalmaztam, melynek segítségével a tevékenységek időtartamára becsléseket készítettem. A doboz ábra elkészítése során kiszűrtem az adathalmazból a kiugró adatokat, így pontosabb statisztikai becslést kaptam. Az átlag kiszámításával a teljes projekt várható befejezésére tettem javaslatot, ami a vevői rendelések szállítási dátumainak pontosabb meghatározására szolgál.Az eredmények összegzésével a vállalatok gyártási folyamatainak újratervezésére teszek javaslatot.
