    Background: Integrating sustainability development' aspects in the design process is becoming, a growth area in companies. Consequently, sustainable product design has to consider the different aspects of sustainability throughout its life cycle phases in addition of other requirements. This integration is becoming more complicated due the difficulty of managing the constraints and alternatives related to the product and stakeholders needs. This study aims to highlights the most used Multi-Criteria Decision Making (MCDM) tools and methods used in sustainable product design process. Contribution: Product design process involves interesting decisional tasks such as the choice of materials, standard parts, technical solutions. Hence, the contribution of this work is to help designer to adopt relevant MCDM tools and methods that can be integrated to other tools to facilitate and to justify their decisional tasks. Method: Several methods have been affected to solve the problems related to this complexity such as MCDM. A literature review was conducted based on Siencedirect and GoogleScholar articles databases. After filtering more than 200 articles only 62 articles were considered to analyze the correlation between sustainable product design and MCDM. Results: Classified MCDM use according to the type of choices to achieve SPD goals. This paper allowed us to find matches between MCDM methods and SPD problem. The majority of case studies result show that a large portion of sustainable design methods, techniques, and tools are applied to the sustainable product’ along its different life cycle phases Conclusion: It is noticed that the use of MCDM methods are an important outcome in the sustainable product design process and deeply helps designers to make suitable choices. Also, several matches relating MCDM, other methods and sustainable product design sphere are discusse

    Aksiomaattinen suunnitteluteoria on ollut kasvavan kiinnostuksen kohteena tiedeyhteisössĂ€ siitĂ€ lĂ€htien, kun Nam P. Suh esitteli teorian 1990-luvulla. SiitĂ€ huolimatta, ettĂ€ aiheesta on tehty runsaasti aktiivista tutkimusta (muun muassa vuotuinen aksiomaattiseen suunnitteluteoriaan keskittynyt konferenssi), kattavia kirjallisuuskatsauksia on kirjoitettu vĂ€hĂ€n. TĂ€mĂ€ tutkimus pyrkii osaltaan tĂ€yttĂ€mÀÀn edellĂ€kuvattua aukkoa aksiomaattisen suunnitteluteorian tutkimuskentĂ€llĂ€, keskittyen julkaisuihin vuodesta 2013 vuoteen 2018. Tutkimus on kirjoitettu jatkumoksi vuonna 2010 tutkijoiden Kulak, Cebi & Kahmaran (2010) julkaisemalle kirjallisuuskatsakuselle. TĂ€mĂ€n vuoksi samankaltainen kategorisointi on implementoitu tĂ€hĂ€n tutkimukseen. Kategorisoinnin perusteina ovat kĂ€ytetty aksiooma, sovellutusalue, metodologia ja mÀÀrittelytyyppi. Sovellutusalueisiin on tĂ€ssĂ€ tutkimuksessa lisĂ€tty ’palvelut’ omana, uutena kategorianaan. TyössĂ€ esitellÀÀn lyhyesti aksiomaattinen suunnitteluteoria ja sen keskeiset osa- alueet, tĂ€rkeimpinĂ€ sunnnittelualueet, suunnitteluprosessi ja suunnitteluaksioomat. Metodologia-osiossa taustoitetaan systemaattisen kirjallisuuskatsauksen soveltamista tĂ€hĂ€n tutkimukseen ja kuvataan prosessin toteutus PRISMA-mallia kĂ€yttĂ€en. Tutkimustulokset kĂ€ydÀÀn lyhyesti lĂ€pi esimerkein kustakin kategoriasta. Tutkimusaineisto esitetÀÀn sekĂ€ lukuina, liitteenĂ€ ettĂ€ graaffeina. NĂ€itĂ€ kirjallisuuskatsauksen tutkimustuloksia verrataan varhemman tutkimuksen vastaaviin. Sovelletun aksiooman suhteen merkittĂ€viĂ€ muutoksia ei ole havaittavissa tĂ€mĂ€n tutkimuksen perusteella aikaisempaan kirjallisuuskatsaukseen verrattuna. Sovellutusaluessa, sitĂ€ vastoin, systeemisuunnittelun osuus on kasvanut merkittĂ€vĂ€sti edelliseen tutkimukseen verrattuna, kun taas ohjelmistosuunnittelun osuus on vastaavasti pienentynyt. Palvelusuunnittelun osuus on verrattain vaatimaton, joskin suurempi kuin esimerkiksi ohjelmistosuunnittelun. TĂ€mĂ€n tutkimuksen perusteella suositellaan jatkotutkimuksia erityisesti aksiomaattisen suunitteluteorian sovellutuksista ohjelmisto- ja palvelusuunnitteluihin sekĂ€ mahdollisista syistĂ€, miksi mainittujen sovellutusaljen osuus tutkimuskentĂ€ssĂ€ on pienehkö.Axiomatic Design theory has been gaining growing interest within a design community since introduced by Nam P. Suh in 1990s. Despite an active research within the field, including yearly international conferences of Axiomatic Design, there is not many literature reviews made of academic publications of Axiomatic Design. This research aims to fulfil previously described gap on secondary research of Axiomatic Design, focusing on papers published between 2013 and 2018. The study is a continuum to previous paper published by Kulak, Cebi & Kahmaran (2010). Therefore, similar categorization based on applied axiom, application area, methodology and evaluation type is applied in this research. In application area, ‘services’ have been added as a new category for this research. Results are compared with previous study. In findings, no siginificant change has happened in applied axiom, Independece axiom still being clearly more popular within academic publications. In application area, however, there are noticeable changes compared to the previous study. Share of system design has increased while softare design has significantly decreased. Future research is recommended to further explore specifically applications of Axiomatic Design in software and in services

    The monograph constitutes a crowning of research led in the field of particular methodology of management science, in the field of enhancing managerial decision-making sub-discipline in frames of the practical stream of the management science discipline. The monograph is a development of the research project in which the elaboration of a scientific method for the enhancement of managerial decision-making processes through the Modular Multicriteria Managerial Decision-Making Model (MMUMADEMM) has been proposed
