Assignment problem (AP) is an entrenched tool for solving engineering and management problems. The Hungarian method is always used to fathom the AP in crisp cases. This paper presents an algorithm of finding the optimum solution of the fuzzy AP by using the modified Hungarian method. This method is utilized to get a minimum assignment cost in the fuzzy environment for a fuzzy AP. Firstly, we use the fuzzy numbers without any transformation. Secondly, the fuzzy AP is transformed into an interval AP based on the α-cut methodology. Then, the interval arithmetic operations and the order relations are applied to get the optimal solution by utilizing the modified Hungarian method. The proposed algorithm requires less efforts and time to reach optimality, compared to the existing methods. Numerical examples are given to ensure the efficiency and the validity of the proposed algorithm. A study on the reuse of many valuable buildings is presented after using different government and service buildings in a manner that does not fit with its original function and heritage value. We offer a solution based on the scientific and realistic basis for requalification according to the variables and requirements of the social, cultural, and economic environments in the environment surrounding the valuable buildings.

Currently, there is a deficit efficient and contextualized design strategies to aid in infection prevention and save health professionals. Thus, the paper's objective is to validate how the room we enthrall can be made safer from the perspective of architectural design with the aim of creating rules for politicians and highlighting the role of the architect in battling diseases. Two hospitals have been considered to apply these conditions to adapt with new polices of infection control. The modifications have revealed good results that the hospitals have been divided into three sections, triaging, isolated patients, and normal patients.

As a result of the political, economic and social changes that Egypt has witnessed recently, which directly affected the urban environment and led to architectural and urban distortion. From this standpoint, the research paper deals with the study of the reciprocal relationship, the most important design principles and aspects for urban environments, the landscape elements, and what are the different variables that constitute them in order to reach an urban model to reduce visual pollution in Egyptian cities. This is done through two main points: The first point depends on studying and identifying the most important design aspects for urban environments, in addition to the various elements of site coordination and what are the variables that constitute them. As for the second point, it is based on finding the interrelationship between the most important design aspects and the variables of the various landscape elements through distributing and analyzing a sample of questionnaires that were distributed to a group of experts in the field of urban design, with the aim of formulating the urban model, the objective of the research study, in order to study the relationships and mutual influences. Between the most important design principles and aspects of the urban environments and the landscape elements and their various variables, to know how to achieve and apply them within the urban environment of Egyptian cities.
