Resource-constrained project scheduling has been a significant and practical problem in recent decades. In this research, besides previous assumptions and models regarding scheduling, the reliability function with a novel approach is included in the model. A new look at the project scheduling problem is pursued by studying the probability of access to renewable resources. The mentioned problem programming model is a mixed nonlinear mathematical model that uses the properties of an exponential function to become a linear programming model, exact optimization software is used to solve it in smaller dimensions, and a genetic algorithm is used to solve it in NP-hard dimensions. The algorithms and statistical analysis results at a 95% confidence level show the proper performance of the genetic algorithm; therefore, this algorithm is more efficient for the proposed model. Using the provided mathematical model, this research leads to decreasing time and lags, decreasing costs, and increasing reliability in multimode activities.

Duration, cost, and resources are defined as constraints in projects. Consequently, Construction manager needs to balance between theses constraints to ensure that project objectives are met. Choosing the best alternative of each activity is one of the most significant problems in construction management to minimize project duration, project cost and also satisfies resources constraints as well as smoothing resources. Advanced computer technologies could empower construction engineers and project managers to make right, fast and applicable decisions based on accurate data that can be studied, optimized, and quantified with great accuracy. This article strives to find the recent improvements of resource-scheduling problems and time-cost trade off and the interacting between them which can be used in innovating new approaches in construction management. To achieve this goal, a state-of-the-art review, is conducted as a literature sample including articles implying three areas of research; time-cost trade off, constrained resources and unconstrained resources. A content analysis is made to clarify contributions and gaps of knowledge to help suggesting and specifying opportunities for future research.

I have to say deepest gratitude only goes to my supervisor Prof. Zhang Limao for his sincere guidance and kind support throughout the research. After the completion of my undergraduate study, I had worked for several years, and I lost. I lost my motivation and didn't know what should I do next. I had tried part-time jobs for years, and out of those experiences, I thought being a teacher may be the right thing for me. I believed I was good at learning and I loved sharing my knowledge and communicating with others.That's why I decided to get back to school, pursuing a doctoral degree so that I could be a teacher one day. To be honest, however, I was not that confident. It took courage for me to make this decision, and I would try my best without doubt, but I also acknowledge that I had left school for too many years, and I wasn't very sure if I could catch up and become a qualified doctoral candidate in time. So, firstly, I have to thank prof. Zhang for giving me the opportunity to be a doctoral student here. Secondly, it was his demanding and supportive supervision that really changed me. I had to admit that I was kind of stressed at the beginning, for that I was way behind from the schedule. I had too much to learn, and it was my own responsibility to catch up in time. However, prof. Zhang tutored me with unbelievable patience. I cannot even remember how many times and how much time prof. Zhang had spent to teaching me even if I made the stupidest mistakes. I just know that I may achieve nothing if without his great patience and valuable, inspiring, and professional tutorial. What's more, he sets an example of being a good supervisor for me. He not only helps me become a qualified doctoral student, but also his professionalism, dedication, and meticulous attitude enlighten me of what a great supervisor is and make me determined to be one as he does. Now, I know how, I am confident and I am resolved that I will become a qualified professor.Surely, I am also deeply grateful to my family, my parents and my beloved sister.You are always there to support. Thank you.
