The aim of the article was to define the internationalization strategies of Polish furniture enterprises, as well as to indicate the instruments of competition used by these companies on the foreign market. Empirical research was carried out in a group of 100 medium and large furniture enterprises conducting export activity. The research identified the most frequently used internationalization strategies by furniture companies, identified the most effective strategies, and identified competition instruments of the greatest importance for Polish furniture manufacturers. The research showed that ethnocentric strategy is most often used in the furniture industry. This strategy is the most effective.

This article deals with the analysis angélique wood (Dicorynia guianensis Amsh.) properties to verify suitability for use in the arrangement of external architecture such as the construction of terraces. Particularly, tests included determination of hardness by the Brinell method and total and partial shrinkage. The presented characteristic of properties was complemented by the analysis of wood colour stability during exposition to natural weathering factors for six months. Changes of particular colour parameters (lightness L*, chroma C*, hue h) were determine as well as the total colour change ΔE*. The colour stability was examined on untreated wood surface as well as on wood finished with clear and colouring oils. It was found that the angélique wood belongs to the group of very heavy wood (specific gravity 807 kg/m3) and is characterized by the favourable technical parameters, primarily the high hardness (average hardness 45,64 MPa). Furthermore, the angélique wood is the wood of average shrinkage (average total shrinkage 14,37%). Dimensional stability does not differ from the properties of wood commonly and successfully used for wooden external construction. The results showed that during external exposition angélique wood became darker.

Further, it was also evaluated if LM facilitated the transition towards Industry 4.0 adoption. The questionnaire-based survey involved 484 furniture manufacturers, of large-size and SMEs. The results found that the adoption of LM was prevalent among large-sized companies, and LM improved product quality and customer satisfaction, while reducing manufacturing lead time in the companies. The 5S method of work place organization, process mapping and waste reduction and elimination were the most common LM tools adopted by the companies. On the other hand, the major challenges encountered when implementing LM were lack of know-how, backsliding to old work ways, and resistance to adopt among the employees. The result also revealed that companies practicing LM also suggested that they were more prepared to adopt Industry 4.0 technologies, as the practice of LM has not only reduced waste on the production shopfloor, but also improved the information flow that is important for digital tools of Industry 4.0.\u0000\u0000","PeriodicalId":8020,"journal":{"name":"Annals of WULS, Forestry and Wood Technology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75642556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
