Dissemination of algorithms for decision-making aiding in the design of furniture and other products made of lignocellulosic materials in the scientific literature. The issue of the proper selection of dimensions of the designed products can be supported with the use of mathematical algorithms built into CAD systems. There are many such algorithms, they have their specificity and areas of application. The article lists a dozen or so of the most popular algorithms of this type, and then checks their prevalence in the scientific literature on furniture design. The result is a point the method (group of methods) that best takes into account the specific features of lignocellulosic materials. The main conclusion is that the most popular algorithms are: the ε-constraint method, genetic algorithms and artificial immune systems. The most popular is the ε-constraint method.

Upowszechnienie w literaturze naukowej algorytmów wspomagających podejmowanie decyzji w projektowaniu mebli i innych wyrobów z materiałów lignocelulozowych. Zagadnienie właściwego doboru wymiarów projektowanych wyrobów może być wspomagane za pomocą algorytmów matematycznych wbudowanych w systemy CAD. Takich algorytmów jest wiele, mają one swoją specyfikę i obszary zastosowań. W artykule wymieniono kilkanaście najpopularniejszych algorytmów tego typu, a następnie sprawdzono ich rozpowszechnienie w literaturze naukowej dotyczącej projektowania mebli. Wynikiem jest metoda punktowa (grupa metod), która najlepiej uwzględnia specyficzne cechy materiałów lignocelulozowych. Główny wniosek jest taki, że najpopularniejsze algorytmy to: metoda ε-ograniczenia, algorytmy genetyczne i sztuczne układy odpornościowe. Najpopularniejsza jest metoda z ograniczeniem.

Analysis of working conditions in terms of ergonomics is an increasingly popular topic among industrial enterprises. This is primarily due to the development of departments responsible for maintaining safe and healthy working conditions, but also awareness of the impact of working conditions on maintaining safety and maintaining the rhythm of work. Care for working conditions translates into the possibility of maintaining the level of activities performed, which indirectly affects the quality of final products. Conducting activities in the field of shaping ergonomic working conditions in the context of continuous improvement based on the Deming cycle and the principles of conceptual ergonomics seem to be a key approach to care for work safety. Treating this process as a continuous and looped process gives you the ability to react quickly and predict adverse effects. However, constant control, observation, and analysis of the possibilities of implementing improvement solutions is important. The purpose of the article is to compare ergonomic working conditions at selected work stations with the assumptions and plans developed before launching the assembly line. The research included a comparative analysis of results in the form of ergonomic score obtained from TiCon software, based on MTM, UAS, and EAWS methods. The research was carried out at the turn of 2016-2020 in an automotive company dealing in the production of passenger car drive system components.

Zmniejszenie różnorodności elementów struktury różnych wyrobów jest korzystne na wszystkich jego etapach funkcjonowania: od projektowania, przez wytwarzanie, użytkowanie, obsługę, po likwidację. W technice stosuje się w tym celu m.in. typoszeregi wyrobów ustandaryzowanych, tworzące ciągi arytmetyczne, geometryczne oraz uporządkowanie modularne.

Reducing the variety of elements of a structure of different products is beneficial at all stages of their functioning: from design, through manufacturing, use, maintenance and disposal. For this purpose, type series of standardised products, forming arithmetic and geometric sequences, as well as modular ordering, are generally used in industrial design. The main way to reduce the diversity of machine parts in a particular series of fasteners is to select its preferred elements. A good example of this approach is the preference of bolt sizes: M6, M10, M16, M24 from a fragment of series comprising: M6, M7, M8, M10, M12, M14, M16, M18, M20, M22 and M24 bolts.
