The notion of using a meta-heuristic approach to solve nonlinear resource-leveling problems has been intensively studied in recent years. Premature convergence and poor exploitation are the main obstacles for the heuristic algorithms. Analyzing the characteristics of the project topology network, this paper introduces a directional ant colony optimization (DACO) algorithm for solving nonlinear ...

In this paper, we describe the design and development of an interactive virtual environment whose objective is to help undergraduate students learn and review the concept and practices of differential leveling. The virtual environment includes realistic terrains and leveling instruments that look, operate, and produce results comparable to the physical ones. It will be integrated in surveying c...

The following paper will describe a methodology for automatically detecting and diagnosing rolling element bearing wear. The techniques involved have been proven in over 15 years of use in a huge variety of environments, machine types and applications. The techniques involved in diagnosing bearing wear will be described in detail and supported by a set of example graphs and an annotated diagnos...

Despite the numerous benefits of formal mentorship for all faculty, it remains underutilized within academy. Specifically, this lack critical support leaves historically marginalized groups, particularly women, underrepresented minorities, as well part-time, intermittent, adjunct, or non-tenure track to struggle with navigating challenging climate higher education. To counter these inherent pow...

This paper explains an implementation model for a new method for Production Leveling designed for batch production system. The main structure of this model is grounded on three constructs: traditional framework for Operations Planning, Lean Manufacturing concepts for Production Leveling and case study guidelines. By combining the first and second construct, a framework for Production Leveling h...

In this paper we present a new algorithm for leveling a discrete terrain using autonomous agents of minimal complexity. Our primary interest is in developing robust strategies for eventual application in underwater construction. Terrain leveling underwater typically involves the use of large and expensive machinery that may be cumbersome to operate. We propose that a swarm of autonomous robots ...

In this paper a new method based on fuzzy theory is developed to solve the Project Resource Leveling Problem in fuzzy environment. Resource Leveling Problem attempts to minimize the resource usage fluctuations in project plan. Assuming that the duration of activities and resource requirements are fuzzy, in this method we compute several project characteristics such as earliest times, latest tim...

nowadays, combination of gps heights with orthometric heights, derived from precise leveling, is broadly used to obtain point-wise solutions of the geoid, which is called “gps/leveling geoid”. the “gps/leveling geoid” is commonly used to constrain the gravimetric geoid solutions in a least squares surface fitting process. in this paper, unlike the usual application, the “gps/leveling geoid” is ...

naming as an inseparable sign of a country’s language has attracted the attention of many linguists to formulate and test hypotheses regarding the culture and language of the people of a certain area. iran appears like a proper destination for conducting a research focusing on naming based on several factors such as geography or chronology. the present article aims to take a specific look at th...
