Due to various added advantages over the conventional material removal processes, non-traditional machining (NTM) processes have now been widely applied in different manufacturing industries. To achieve the desired response values, it is always recommended to operate these NTM processes at their optimal parametric settings. Various single response optimization techniques are already available to determine the optimal combinations of NTM process parameters for achieving maximum or minimum value of a single response. In this paper, a multivariate quality loss function approach is adopted for simultaneous optimization of responses for three NTM processes. It is observed that this approach outperforms the other multi-response optimization techniques, like desirability function, distance function and mean squared error methods with respect to the achieved re-sponse values. With modification of the corresponding objective function and constraints of the de-veloped non-linear programming problem, it can be effectively applied to any non-traditional as well as conventional machining process as a multi-objective optimization tool.

Teamwork, for competitive advantage, involving techno-socio-cultural aspects of organizations for engineering developments, is gaining importance rather rapidly due to advent of globalization. The purpose of this study is to identify the importance of teamwork culture for new product develop-ment (NPD) success through enriching the NPD team’s capability in Indian manufacturing industries. It accumulates the teamwork culture dynamics and practices, their interrelationships and their combined impact on NPD team’s capability in terms of technological developments for NPD success. This practical analysis collects primary data from 263 design and development experts from Indian engineering manufacturing companies. Structural equation modeling (SEM) approach is applied to investigate the interrelationship among associated variables of teamwork culture and NPD team’s capability for NPD success. Concurrent engineering team (CET), communication infrastruc-ture (CI), system integration (SI) and result orientation (RO) have been recognized as allied factors of teamwork culture. Successful adoption of associated variables ensures NPD success through influencing NPD team’s capability which in turn articulated by technological developments. The realization of combined impact of teamwork and its allied variables escalates technological developments which in turn enriches NPD team’s capability assuring organizational success. The result indicates that both CI and SI support CET for accelerating NPD team’s capability through technological developments. Besides, CET motivates innovation orientation most precisely referred as RO for escalating NPD team’s capability through technological developments for innovation.

Flexible Manufacturing System (FMS) is a compound system containing essentials like workplac-es, computerized storing and recovery systems, and material control devices such as automatons and automated guided vehicles (AGVs). In this paper, an attempt is made to study concurrently the machine and vehicle planning features in an FMS for minimization of the makespan. Planning is concerned with the distribution of partial resources to tasks over time and it is a resolution making procedure. It associates the processes, time, cost and overall purposes of the company. In this work, Nawaz-Enscore-Ham (NEH) heuristic algorithm is implemented to solve the scheduling problems in FMS. Eighty two problems and their existing solutions with different approaches are examined. The preliminary results indicate that the NEH heuristic algorithm provides better solu-tions with less computational time.

It is a commonly visible scenario in todays’ market, especially in small and medium sized enterpris-es (SMEs), where the focus is on quantity rather than quality. This paper explains the common high rejection problem of a SME and how the productivity levels were enhanced after the successful implementation of Six-Sigma DMAIC methodology. Once the project completion industry was able to acquire many tangible and intangible benefits, this paper offers a systematic step by step illustration of DMAIC methodology to help the other firms start similar productivity improvement initiatives.

The objective of the present study is to bring out a multidimensional metric to measure service quality delivered by employees serving in Indian small & medium manufacturing enterprises. 144 executives working at top/middle level in different small-medium manufacturing units of north India responded to a questionnaire survey. The respondents were asked to assess service quality being delivered by the shop-floor workers serving their respective units on the 1-5 perception scale. Application of exploratory factor analysis resulted in an interpretable latent structure comprising of 5 determinants and 22 indicator items. Confirmatory factor analysis condensed this scale to bring out the final scale 4 determinants viz., Dependability, Agility, Professionalism and Understanding with 13 indicator statements. This scale thus emerged is tested for validity and reliability using established tools. The study provides a framework to SME managers to assess services of their workforce. It also contributes to researchers to build up more such metrics for similar situations in other sectors so that more concrete generalizations can be made.

This paper compares and evaluates the performance of five different conventional job selection dis-patching rules for scheduling of multi-load automatic guided vehicles (AGVs) serving for material handling operations in variable sized flexible manufacturing system (FMS) layout. Four sizes of FMS layout are considered for the performance evaluation of the five types of conventional job se-lection dispatching rules. The FMS layouts under consideration are served by the two multi-load AGVs. The multi-load AGVs cruises under machine initiated the nearest vehicle (NV) dispatching rule for the material handling activities at all work centers (WCs) for all four sizes of FMS layout. Four sizes of FMS layout produce five different types of parts and consist of three, six, nine and twelve work centers and loading-unloading centers, respectively. In the simulation test, it is found that the identical destination first (IDF) job selection rule having selection criterion based on the destination similarity of two picked up jobs outperforms all other job selection dispatching rules for an overall production rate of the FMS (parts/hr) in all four FMS layouts.

Variation exists in all processes. There is not even a single process that is completely true. Measuring the trueness of the process is itself a process which can also imitate the process variation. Therefore, measurement system should be strong enough to wager on the trueness of the process. This paper is an attempt to indicate the true method and substantiate the use of measurement system analysis (MSA) by using it in two different environments i.e. in manufacturing as well as process industry. Also, a comparison among various analyzing techniques has been drawn for authenticating the candid method followed by an evaluation using fuzzy TOPSIS for authenticating the results of comparison. The organization’s type, also, strongly influences the performance of MSA as revealed in the conclusion of the article. The results calculated by various methods and in both environments were discussed and as a result ANOVA comes out to be the best method. The application of correct MSA is highly required which ultimately results in increased organizations’ performance. The study is one of its type and will motivate the researchers and industrialists to use and explore the new and efficient ways of MSA.

These ultrasound irradiation and conventional technique reaction proceed efficiently in water in the absence of organic solvent. In comparison with conventional methods, our protocol is convenient and offers several advantages, such as shorter reaction time, higher yields, milder conditions and environmental friendliness.

The derivatives of 2,6-dihydroxyacetophenone[4]arene were synthesized via one-step in the presence of base catalyzed cyclocondensation reaction of equimolar volumes of different aliphatic aldehydes and 2,6-dihydroxyacetophenone. All the compounds were purified by column chromatography and characterized by ¹H-NMR Spectroscopy, ¹³C-NMR Spectroscopy, IR Spectroscopy, and Mass spectrometry techniques. The compounds were provided with good yield and can be successfully useful for various amino acid detection because of the four ketone groups in 2,6-Dihydroxyaceto-phenone[4]arene were able to react with the amino group of amino acid to give a stable product formation. It was caused by the intermolecular hydrogen bonded between the two groups, ketone and carboxylic group of amino acid. This recognition of amino acid was carried out in UV-vis spectroscopic technique.
