“…In order to execute a Six Sigma project, activities under the five phases, namely, define, measure, analyse, improve and control, are required to be carried out. These phases are shortly denoted as DMAIC [18,28]. The propagandists of Six Sigma emphasised that while carrying out DMAIC, the members of the Six Sigma team need to undergo relevant and result-oriented training to execute the projects effectively.…”

“…Although several approaches and principles have been suggested and critical success factors of implementation have been identified by the researchers [23] to enhance the performance of Six Sigma projects in companies, majority of these efforts have been made by keeping DMAIC as the framework [23,28,29]. Although the belt-based training system is prescribed as yet another cornerstone of Six Sigma framework, many case studies reporting only the implementation of DMAIC to achieve the goals of Six Sigma (without the implementation of belt-based training infrastructure) have been reported in the literature arena [8,15,30,[32][33][34].…”

From the middle of 1980s, Six Sigma concept emerged in Motorola. Because Six Sigma implementation facilitated the companies to achieve profitability, it was implemented subsequently in many parts of the world. Six Sigma is implemented by majority of the companies situated in the world by applying DMAIC (stands for define, measure, analyse, improve and control) phases. Meanwhile, there have been reports of the failures of implementing Six Sigma programmes presumably due to the failure to consider and apply the appropriate tools and techniques. In this regard, it is to be noticed that Poka-Yoke, which is a tool that can be used to achieve zerodefect manufacturing, has the potential to support the implementation of DMAIC phases of Six Sigma. On deriving this observation, the literature navigation reported in this paper was carried out to understand the essence of Six Sigma and PokaYoke as well as the trend of applying Poka-Yoke in DMAIC phases. In the literature survey conducted to carry out this literature navigation, the researches on applying Poka-Yoke concept in DMAIC phases were studied by referring to the relevant research papers. It has been pointed out that the Poka-Yoke solutions suggested in these research papers were not actually implemented in real-time scenario. Hence, this article ends with a suggestion that future researchers can make efforts to actually implement Poka-Yoke technique in DMAIC phases for achieving the goals of Six Sigma.

“…The paper [3] describes the calculation of the non-failure probability (reliability index) of reinforced concrete beams with carbon-fiber reinforced polymers (CFRP). A statistical analysis to control cracking in reinforced concrete structures based on the "68-95-99.7 rule" is presented in [4]. The paper [5] discusses the risk assessment of corrosion in the rebar of concrete structures and evaluation of their reliability and durability by probabilistic and statistical methods.…”

Reliability analysis of the existing reinforced concrete beams with normal cracks by rebar strength criteria

et al. 2020

The paper describes the problem of the reliability analysis for individual reinforced concrete (RC) beams by the rebar strength criterion in cross section with a normal crack. It is proposed to evaluate the stress in the rebar by measurements of the crack width at the level of the rebar using the functional dependence of the crack width and the strain (deformation) in the reinforcement. It is also proposed to replace the modulus of elasticity of steel reinforcement on the secant modulus of elasticity, taking into account the increased reinforcement strain in cross section with crack. The work considers two options of the crack width in beam: less and greater than the ultimate crack width. The reliability analysis of RC beams by the rebar strength is based on the possibility theory and fuzzy set theory by the reason of small statistical data from measurements on existing individual RC beams. The use of offered reliability analysis methods will allow preventing the failures of reinforced concrete beams and in some cases to obtain economic benefit from the possibility of further operation of RC beams with cracks, even with a crack width more than ultimate value.

Retrofitting Performance of Reinforced Concrete One Way Slab

et al. 2016

Cracks in concrete structure have always been a big threat on the strength of the concrete. Crack is one of the common deterioration observed in reinforced concrete beams and slabs. Concrete cracking is a random process, highly variable and influenced by many factors. To restore the structural capacity of the concrete damages, retrofitting and strengthening are required. There are several techniques that are used for retrofitting and strengthening reported in the literature [1], [2], [3]. This paper investigates the strength performance of retrofitting and strengthening methods of reinforced concrete one-way slab. Flexural bending test are performed on three different concrete slab of size 1000 mm x 500 mm x 75 mm. The methods that are used for retrofit are epoxy injection and patching and for the strengthening is lamination of carbon fiber reinforced polymer. The slabs were loaded to a certain stage where the cracks were formed for retrofitting and strengthening procedure. The achieved failure mode and load capacity of the concrete slab were observed. The repaired techniques for restoring and improving the structural capacity of cracked concrete slabs were analyzed. The ultimate load achieved for the epoxy injection laminate was 19.60 kN followed by CFRP laminate and patching that were 17.64 kN and 17.03 kN respectively. While the deflection value for the three specimens were 14.42 mm, 4.49 mm and 7.036 mm.
