“…In Parade Game, Tommelein (1999) analyzed the influence of variation in work flow on the performance of the entire project through simulation and confirmed Alarcon (1999) evaluated the influence of variation in work flow on the cost and schedule of the project through a simulation called Playing Games. Kim (2001) understood the Lean Principle that "Enhancement of reliability in schedule management contributes improvement in work flow, productivity, and quality" and proposed a schedule information model that can be utilized in the detailed planning stage and a subsequent method for variation control.…”

The majority of currently used construction productivity management systems rely on result-based management techniques, which have difficulties in managing in uncertain environments. Massive amounts of time and resources are wasted due to conflicts between works and constraints in space, etc. Hence, we need to recognize the limitations of existing result-based management systems and suggest a productivity management index that is expected to ensure that the issues of productivity reduction are properly controlled.Work flow refers to the progression of work in a limited time and space. Schedule delay and expense waste can be controlled by managing the work flow. Measurement of work flow is evaluated using 3 indices: Continuity Index, Variation Index, and Productivity Index. Therefore, this research suggests an evaluation and measurement system for work flow that shows the productivity of construction work both directly and indirectly, and thereby aims at an improvement in project performance by using a target index.

“…Since Activity #2 in Figure 2 requires the work finished by Activity #1 (prerequisite), the amount of WIP inventory may affect the productivity of Activity #2: if there is insufficient inventory, Activity #2 may have idle resources and experience lowered productivity. Thus, the amount of WIP inventory can function as a buffer to protect the productivity of a subsequent activity [6,8,13]. …”

“…While the sequence of activities in construction projects is not typically changeable, productivity in each activity may be changed depending on other factors such as job site conditions or the amount of resources available [11,12]. When subcontractors' productivities are well balanced (similar to) each other, operations by multiple subcontractors can be performed smoothly [13]. However, if subcontractors' productivities are not balanced with each other, some subcontractors may need to wait for work completed by an upstream subcontractor, and thus the overall project duration is increased [8].…”

Fast delivery of construction projects provides more value to project owners. Batch production, which is production not in single pieces, but in batches, is a common approach in repetitive construction projects such as multi-unit residential building construction projects. In batch production, the use of a small batch size allows the early start of subsequent activities, and thus can lead to early completion of projects. In addition to batch size, balance between productivities in construction activities can affect project duration. However, the impact of the balance between productivities with regard to their order on project duration has not been studied. The main goal of this study is to test a hypothesis, which is that the order of construction activities' unbalanced productivities affects the amount of time reduction that can be achieved by using a small batch size. A computer-based simulation model was developed, and five different cases were simulated to test the hypothesis. The conclusion of the simulation result is that the order of productivities does not affect the time reduction achieved by using a small batch size. It is expected that the findings of this study can help general contractors make decisions in terms of batch size.

Batch production is common in repetitive construction projects, and it is not unusual for different batch sizes to be used by contractors in one project. While several scheduling methods, such as the Linear Scheduling Method (LSM) and the Repetitive Scheduling Method (RSM) have been proposed and used, no mathematical method for repetitive construction projects has been developed, and it is difficult to consider different batch sizes with the existing methods. An original mathematical algorithm for scheduling repetitive projects with different batch sizes is proposed in this study. This algorithm is illustrated with assumptions of resource continuity and single path in a project and introduces new terms, control batch and critical batch. The algorithm logics and mathematical equations are validated by comparison with the outcomes from a graphical scheduling approach through a simple and practical hypothetic project. As a result, it is expected that the proposed algorithm can be easily adapted and extended to computer software for scheduling, and can be a starting point for research on batch size management in repetitive construction projects.
