Statistical process control ($SPC$), an internationally recognized technique for improving product quality and productivity, has been widely employed in various industries. $SPC$ relies on the use of control charts to monitor a manufacturing process for identifying causes of process variation and signaling the necessity of corrective action for the process. Fuzzy data exist ubiquitously in the ...
Introduction and purpose: Industrial accidents are highly prevalent. Regarding this, identification of the risk factors of occupational accidents can be helpful in preventing the occurrence of this type of accidents. The aim of this study was to assess the risk factors in the incidence of occupational accidents and prioritize the severity of the identified risks in order to ...
Shewhart charts are the main tools for statistical process control. They are used for detecting assignable causes which affect quality of process output. From them, X and MR charts are two univariate control charts for monitoring mean and variation of measurable quality characteristics. The main drawbacks of these charts are: weakness of X chart against non-normal distribution of process data,...
Abstract Business continuity depends on the quality of management individual processes. The team strives to anticipate all possible threats and define protective measures. In event COVID-19 pandemic enterprises were not prepared for such threats. Therefore, an important role is played by health safety inspector who should be involved in company process. impact aspects work environment efficienc...
We present a combinatorial solution to the problem of determining the number of lozenge tilings of a hexagon with sides a, b + 1, b, a + 1, b, b + 1, with the central unit triangle removed. For a = b, this settles an open problem posed by Propp 7]. Let a, b, c be positive integers, and denote by H the hexagon whose side-lengths are (in cyclic order) a, b, c, a, b, c and all whose angles have 12...
Unit-load warehouses store and retrieve unit-loads, typically pallets. When storage and retrieval operations are not coordinated, travel is from a pickup and deposit (P&D) point to a pallet location and back again. In some facilities, workers interleave storage and retrieval operations to form a dual-command cycle. Two new aisle designs proposed by Gue and Meller (2006) use diagonal aisles to r...
the purpose of this study was to investigate the relationship between teachers’ class management practices with students’ self- regulated learning and academic self-efficacy. in this study relating to the management class, three dimensions, (training management, people management and behavior management) and three style (interventionist, interactionist and non-interventionist) was considered. r...
learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...
Various lean management techniques (e.g., Ishikawa Diagrams, Total Quality Control, and Just-inTime) can be applied to improve the efficacy of online instructional systems. Problems with online pedagogy and errors or defects in course design can be analyzed by directed processes through techniques such as root cause analysis (RCA), resulting in determination of secondary and primary causes of a...
