Transport is one of the factors influencing the development of metropolitan areas. However, for its efficient work, numerous optimizations are required. Main tasks are shortening travel time, improving service quality and increasing the number of passengers served. The author has presented current studies on the field in optimization of public transport, mainly ways to optimize the transport network construction, based on large data sets about the population and their communication behaviour. Methods of combining various types of public transport with each other are presented. In the paper also are presents authors studies on the communication accessibility within the city of Cracow. Estimated distances from buildings to various types of public transport stops. The results were presented in aggregated form. Calculated communication speed of three types of public transport functioning in Cracow has also been discussed.
In this article, authors analyze methods of the analysis of data integrity, security and availability loss results for business processes. Assessing those results, one can judge the importance of a process in organization; thus, determine which business process requires more attention. The importance of those processes can be determined with Business Impact Analysis (BIA). In article, first phase of BIA is presented – in specific, a construction of Business Impact Category Tables, Loss Levels and process weight calculation methods. A variety of weight calculating methods is presented. Authors also present their proposed method – square sum percentage – as a solution eliminating problems of other weight calculation methods in business impact analysis.
Public Supply of Rental Housing under The National Housing Program – Possible Scenarios of Changes in the Rental Market. The aim of the study is to conduct analyzes of possible scenarios of changes in the housing sector after launching the Plus Apartment Program. Therefore, the purpose of housing policy should be to increase the availability of apartments in the form of rental. The research problem is the answer to the following questions: Is it feasible to intervene in the construction market to increase rental supply? What impact on the private rental market may have on the supply of public housing about the rent lower than the market? What impact can the supply of housing under the Plus Apartment Program on the investment and rental of housing for social building society? In which municipalities and on what scale should I implement the Plus Apartment Program? The study hypothesized that the impact of the public supply of apartments for rent under the Plus Apartment Program on residential markets will depend on local conditions of market development and local housing situation.
