Abstract. Budget analysis of a tendency equation is widely utilized in numerical studies to quantify different physical processes in a simulated system. While such analysis is often post-processed when the output is made available, it is well acknowledged that the closure of a budget is difficult to achieve without temporal and/or spatial averaging. Nevertheless, the development of errors in such calculations has not been systematically investigated. In this study, an inline budget retrieval method is first developed in the WRF v3.8.1 model and tested on a 2D idealized slantwise convection case with a focus on the momentum equations. This method extracts all the budget terms following the model solver, which gives a high accuracy, with a residual term always less than 0.1 % of the tendency term. Then, taking the inline values as truth, several offline budget analyses with different commonly used simplifications are performed to investigate how they may affect the accuracy of the estimation of individual terms and the resultant residual. These assumptions include using a lower-order advection operator than the one used in the model, neglecting grid staggering, or following a mathematically equivalent but transformed format of the governing equations. Errors in these post-processed analyses are found mostly over the area where the dynamics are the most active, thus impairing the subsequent physical interpretation. A maximum 99th percentile residual can reach >50 % of the concurrent tendency term, indicating the danger of neglecting the residual term as done in many budget studies. This work provides general guidance not only for budget diagnoses with the WRF model but also for minimizing the errors in post-processed budget calculations.

In this paper, we consider a two-echelon supply chain in which one warehouse provides a single product to N retailers, using integer-ratio policies. Deterministic version of the problem has been widely studied. However, this assumption can lead to inaccurate and ineffective decisions. In this research, we tackle the stochastic version of two-echelon inventory system by designing an extension of a well-known heuristic. This research considers customer demands as following a normal density function. A set of 240 random instances was generated and used in evaluating both the deterministic and stochastic solution approaches. Due to the nature of the objective function, evaluation was carried out via Monte Carlo simulation. For variable demand settings, computational experiments shows that: i) the use of average demand to define the inventory policy implies an underestimation of the total cost and ii) the newly proposed method offers cost savings.

Practical Model

Purpose Road construction projects are one of the strategic industries in each country and their construction and development requires spending huge funds. Regarding the increased demand and resource constraints; a technique which reduces costs by maintaining and improving the functioning is of great importance for the authorities of each country. Value engineering is a comprehensive and coherent means based on innovation and team work which, in addition to maintaining the quality and improving the project function, reduces its cost and is not limited to the design and construction phase; however, it includes exploitation and maintenance as well. This study aims to present a practical model for the implementation and application of value engineering process in a construction project located in a special region (in terms of tourism, positioning in an economic growth path, and the East-West strategic axis of the region). In this regard, after reviewing the advisor's design, considering the interests of the project stakeholders, reviewing design criteria and assessment methods and with the use of value engineering techniques, a new option was presented which led to a significant reduction in costs and time and an increase of quality, safety, and environmental factors. Finally, including initial costs, repair, maintenance, income and expenses, the relative value index of this option, compared to the advisor's option, increased from 0.9 to 3.5. Based on the increased need for development of roads in the country, exploiting this model in similar projects can significantly improve the project value and the effectiveness of investments. Design/methodology/approach This research project was selected with regard to the extremely high credit of the project and its potential in terms of Value Engineering implementation. In this study, technical and financial information were first collected after forming a value engineering team including a value engineering expert who was responsible for coordinating the work, some representatives of the employer, designer, executor, and budget estimator. In functional analysis phase with the use of FAST graph, advantageous, costly, and risky functions were identified. In the creativity phase, ideas related to selected functions were created and investigated and developed in the evaluation phase. Finally, calculating the value index, two variants with higher value index than the baseline plan, were proposed and implemented. Findings Since the determining criteria of designing and implementation of road construction projects including increased safety, reduced travel time, user satisfaction, ease of implementation, cost of construction and maintenance and so on are almost similar in most projects, using this study results and implementing its practical framework in other construction projects can be beneficial. These parameters lead to an increase in quality, value, and safety of the project. With regard to done steps and resulted incomes, this essay can be known as a practical and theoretical model to promote the value of crucial projects especially in developing countries. Research limitations/implications Sanandaj-Hamedan road with the length 176km connects central provinces of Iran. This study is regarding the first part of this route. Based on the specific topography of the region and the existing road limitations, selecting a good variance with all the features of an ideal road from geometric, economic, and safety aspects is a difficult task. Originality/value Employers and project sponsors are always looking for products with greater value and lower cost; therefore, present a practical model for the implementation and application of value engineering process in a construction project and providing a similar work experience can encourage the use of value engineering techniques and significantly improve the project value and the effectiveness of investments.
