Nowadays, we observe two trends in planning issues related to work which are not detached from the past and are actually connected to it.The first trend is the opportunity for education and acquiring a job based on qualifications and disregarding the gender, which allows women participation in society and especially in jobs which were considered as men jobs.The second trend is about the development of using financial and labor resources, in the other words preparing the grounds for more utilization of capitals through labor.Women participate in all occupations of different nature ranging from mine workers to lawyers, surgeons, politicians, and astronauts; hence preparation of theoretical basis for social, cultural and moral to preserve women respect and values is quite essential.

When considering the durability of reinforced concrete structures, Persian Gulf is one of the most aggressive exposure environment in the world. In this region, chloride diffusion and chloride induced reinforcement corrosion; usually leads to a reduced service life of concrete structures and causes significant losses for Persian Gulf states.The paper presents a summary on the state of durability of concrete structures, and the repair of affected structures in the Gulf region. Durability and service life based design is one of the best methods to improve performance of reinforced concrete in harsh environment. Considering the design methods, DuraPGulf, as a new service life design model, provides a realistic prediction of corrosion initiation for reinforced concrete structures in Persian Gulf region.

Decision making is one of the most important and critical tasks for the managers. Hence, providing techniques and methods which facilitate decision making process is a matter of great significance. In this research, by using one of the most applicable multi-scales techniques named Topsios together with Delphi, an applicable model is provided for purchasing strategic equipment (when having several options and criteria). The results of sensitivity analysis on the model indicate high efficiency of this technique.

Port and waterway risk management is an essential way for safe port operation. The waterway risk management is capable of:a. Assessing the risk in ports or waterways, comparing to the risk level considered by authorities: the elements that can be taken into consideration include those related to vessel conditions, traffic conditions, navigational conditions, waterway conditions, immediate consequences and subsequent consequences;b. Identifying appropriate risk control options to decrease the risk to the level considered to be acceptable: The risk control options available include improved co-ordination and planning; training; rules and procedures including enforcement, navigational, meteorological and hydrographical information; radio communications; active traffic management and waterway changes.c. Assessing the risk level of existing ports and waterways to determine the probable risk level. The assessment then indicates whether the existing risk level in the waterway is:1. Acceptable, and no further work is needed unless changes occur in important criteria, such as the traffic pattern or the types of ships using the waterway;2. Negligible, but the risk control options necessary to make the risk level of the waterway acceptable have been identified adequately;3. Not acceptable, and more detailed study is necessary to enable the risk control options that will make the risk level of the waterway acceptable to be identified adequately.The six elements which have considered for evaluation of risk in waterways are as follows: 1. Vessel conditions -the quality of vessels and their crews that operate on the waterway.2. Traffic conditions -the number of vessels that use a waterway and their interactions.3. Navigational conditions -the environmental conditions that vessels must deal with in a waterway relating to wind, currents and weather.4. Waterway conditions- the physical properties of the waterway that affect a vessel manoeuvre.5. Immediate consequences -the immediate impacts of a waterway casualty.6. Subsequent consequences -the subsequent effects of waterway casualties that may be felt hours, days, months and even years afterwards. At the end, waterway risk management, if applied properly, could promote safety of port and waterway.

A considerable part of academic sciences, heretofore, have been formed on the basis of analytic thinking. In this style of thinking, the first step in problem solving is decomposition of the problem to its components. Afterward, it is assumed that solving the problems in part would lead us to solving the whole problem. But success in this procedure of problem solving totally depends on two prerequisites. The first prerequisite is that those decomposed parts have not any bilateral or multilateral interconnections. And the second one is that the relationships between parts should be linear. Just based on these two prerequisites, it is logical and mathematically rational to apply decomposition of the problem for solving it.But these prerequisites do not exist in the phenomena we call it systems. Ports are typical examples of systems; therefore we need systematic thinking to be able to appropriately manage it.In spite of just about 50 years of introduction of systematic thinking in academic area, this approach, because of its usefulness in improving quality of management has gradually dominated in style of organizations management. A brief review of the most attractive consultancy services- BSC, strategic management, TQM, management flights simulators to just mention - shows the need of management consultancy market to these systematic thinking based services.System Dynamics (SD), Peter Senge define it ,in its well known book- fifth discipline, as a necessity for learning organizations, is a major field evolved based on systematic thinking.It seems that ports as a typical example of interconnected and complex systems, have a good consistency to apply this modeling methodology in decision making level. In this paper, the general aspects of SD modeling and its consistency with port decision environment have been discussed.
