Taking into account the expansion of infrastructure and the growth of hospitals, as well as the increase in the influx of patients, the manual preparation of therapies, in particular, regenerative therapy, becomes ineffective and causes frequent dissatisfaction and complaining of patients. Taking into account the large number of factors forming the schedule, the task of multicriteria optimization is presented in accordance with strict restrictions and immediate wishes of patients. This task can be decomposed into several subtasks that require development of: a reference schedule that would satisfy the strict restrictions imposed by the domain; a method for evaluating the reference schedule and intermediate schedules; the method of optimization of the reference scheduling in order to improve the estimated results. In the course of solving these problems it is necessary: to carry out the construction of relevant criteria for evaluating the quality of the decomposition and turn their qualitative values into quantitative forms; carry out the transition from multi-criteria optimization to one-criterion by minimizing the set of evaluation criteria in the scalar value that can be used in the process of optimization; to avoid local optimum and reach the global optimal solution. The article is devised a method of multicriteria assessment and optimization of medical institutions’ schedules, based on the use of automatic theory to construct the reference scheduling of the functioning of the clinic, the application of methods and means of fuzzy logic and evolutionary algorithms. Using an automated system of construction, multicriteria assessment and optimization of schedules of medical institutions can reduce the amount of manual work, as well as increase the level of satisfaction of patients with the quality of regenerative therapy.

The article presents issues relating to designing and improvement of manufacturing processes based on a modelling and simulation method. The 3D model of a production line has been designed and simulation experiment, conducted on the Arena model prepared in a versatile package for modelling and simulation of manufacturing systems and representing functioning of the system, has been carried out. The results obtained from the experiment and analyses of time and ergonomics of work at a work station were subject to multi-criteria assessment based on a point-by-point method of assessment according to Yager.

Occupational health and safety management systems apply audit examinations as an integral element of these systems. The examinations are used to verify whether the undertaken actions are in compliance with the accepted regulations, whether they are implemented in a suitable way and whether they are effective. One of the earliest solutions of that type applied in the mining industry in Poland involved the application of audit research based on the MERIT survey (Management Evaluation Regarding Itemized Tendencies). A mathematical model applied in the survey facilitates the determination of assessment indexes WOPi for each of the assessed problem areas, which, among other things, can be used to set up problem area rankings and to determine an aggregate (synthetic) assessment. In the paper presented here, the assessment indexes WOPi were used to calculate a development measure, and the calculation process itself was supplemented with sensitivity analysis.

Przygotowanie inwestycji mieszkaniowej zgodnie z oczekiwaniami nabywców wymaga od dewelopera dużego doświadczenia i dobrej znajomości rynku, mieszkaniowego. Preferencje osób poszukujących mieszkań są bardzo zróżnicowane, dlatego kluczowe jest poznanie czynników, które brane są pod uwagę przy zakupie mieszkania. Od tego, w jakim stopniu oferowane mieszkania będą spełniać wymagania nabywców zależy poziom ich sprzedaży, który przekłada się na wysokość uzyskanego dochodu z ich sprzedaży. Poznanie preferencji nabywców mieszkań wymaga przeprowadzenia szczegółowych badań wśród potencjalnych nabywców, których celem jest wyłonienie czynników branych pod uwagę przy wyborze mieszkania oraz określenia ich wpływu na podejmowaną decyzję. W artykule przedstawiono metodę, która ma wspomagać dewelopera przy podejmowaniu decyzji odnośnie sposobu opracowania koncepcji budynku odnoszącej się do rozwiązań projektowych i materiałowych, jego lokalizacji oraz uatrakcyjnienia oferty sprzedaży mieszkań.

Preparation of a residential project in accordance with the expectations of a buyer requires from a developer a lot of experience and a good knowledge of housing market. Preferences of people looking for flats are very diverse, therefore, it is essential to know the factors which are taken into consideration when buying a flat. The level of flats sale and income gained from it depend on how much the offered flats meet the requirements of buyers. Understanding the flats buyers’ preferences requires a detailed study among potential buyers that aims at identifying the factors taken into consideration while choosing a flat and determining their influence on the made decision. In the article, the method is presented which supports a developer in making decisions regarding the development of a building concept in relation to design and material solutions, its location and making the offers of flats for sale more attractive.
