Importance of Technological Innovation for SME Growth: Evidence from India
This paper probes the drivers, dimensions, achievements, and outcomes of technological innovations carried out by SMEs in the auto components, electronics, and machine tool sectors of Bangalore in India. Further, it ascertains the growth rates of innovative SMEs vis-à-vis non-innovative SMEs in terms of sales turnover, employment, and investment. Thereafter, it probes the relationship between innovation and growth of SMEs by (i) estimating a correlation between innovation sales and sales growth, (ii) calculating innovation sales for high, medium, and low growth innovative SMEs and doing a aggregate one-way ANOVA, and (iii) ascertaining the influence of innovation sales, along with investment growth and employment growth on gross value-added growth by means of multiple regression analysis. The paper brings out substantial evidence to argue that innovations of SMEs contributed to their growth.Technological innovations, sales growth, auto components, electronics, machine tools, Bangalore

Some PC-based Heuristics For Employee Pick-up Vehicle Routing Problem And Influence Of Spatial Demand Distribution
Experimental Analysis of Some Variants of Vogel’s Approximation Method.
This paper presents a variant of Vogel's approximation method (VAM) for transportation problems. The importance of determining efficient solutions for large sized transportation problems is borne out by many practical problems in industries, the military, etc. With this motivation, a few variants of VAM incorporating the total opportunity cost (TOC) concept were investigated to obtain fast and efficient solutions. Computational experiments were carried out to evaluate these variants of VAM. The quality of solutions indicates that the basic version of the VAM coupled with total opportunity cost (called the VAM-TOC) yields a very efficient initial solution. In these experiments, on an average, about 20% of the time the VAM-TOC approach yielded the optimal solution and about 80% of the time it yielded a solution very close to optimal (0.5% loss of optimality). The CPU time required for the problem instances tested was very small (on an average, less than 10s on a 200MHz Pentium maxjhine with 64MB RAM)
Development of Dispatching Rule based Heuristic Algorithms for Real-Time Dynamic Scheduling of Non-identical Parallel Burn-in Ovens with Machine Eligibility Restriction
This study addresses a new problem, close to real life on scheduling of non-identical parallel Burn-in ovens (BO) in Semiconductor Manufacturing (SM) industry to minimize Total Weighted Tardiness (TWT) of the jobs. Due to computational intractability in using mathematical programming approach, many researchers considered Dispatching Rules (DR) based heuristic algorithm in SM industry for scheduling of various batch processing machines, including BO. However, there is no study that compares the various DR considered for scheduling of BO in general, particularly in (a) Dynamic Scheduling (DS) of Non-identical Parallel Burn-in Ovens (NPBO) with Machine Eligibility Restriction (MER) and (b) Real-Time DS (RTDS) of NPBO with MER. To address this research gap, this study proposed 25 variants of DR based Heuristic Algorithm (DR-HA). Empirical and statistical performance analyses, carried out with 240 test data, revealed that variants of DR-HA that outperform during DS-NPBO with MER also outperform in RTDS-NPBO with MER. Furthermore, this study gives an important inference that whenever any RTE occurs in RTDS-NPBO, there is no need to modify existing efficient algorithm or no need to develop new algorithm for RTDS-NPBO and updating input data related to type of occurred RTE is sufficient before running existing efficient DR-HA for DS-NPBO
Transport analytics in action: a cloud-based decision support system for efficient city bus transportation
Optimising city bus transport operations helps conserve fuel by providing the urban transport service as efficiently as possible. This study develops a Cloud-based Decision Support System (C-DSS) for transport analytics. The C-DSS is based on an intelligent model on location of depots for opening new depots and/or closing a few existing depots and allocation of city-buses to depots. The C-DSS is built on the Cloud Computing architecture with three layers and includes an efficient and simple greedy heuristic algorithm. Using modern information and communications technology tools, the proposed C-DSS minimizes the cost of city bus transport operations and in turn to reduce fuel consumption and CO2 emissions in urban passenger transport. The proposed C-DSS is demonstrated for its workability and evaluated for its performance on 25 large scale pseudo data generated based on the observation from Bangalore Metropolitan Transport Corporation (BMTC) in India
