The first industrial revolution (industry 1.0) earned millions for textile mill owners while the second industrial revolution (industry 2.0) opened the way for tycoons and captains of industry like John D. Rockefeller, J.P. Morgan and Henry Ford. The third industrial revolution (industry 3.0) engendered technology giants like Apple and Microsoft, and made magnates of men like Steve Jobs and Bill Gates. Now, the race for the fourth industrial revolution (industry 4.0) is on and there is no option, every country whether developed or developing must participate. Many countries have positively responded to industry 4.0 by developing strategic initiatives to strengthen industry 4.0 implementation. Unlocking the country’s potential to industry 4.0 has been of interest to researchers in the recent past. However, the extent to which industry 4.0 initiatives being launched globall...

To investigate the effect of alkali treatment on the mechanical properties of the resultant composites, the sisal fabrics were soaked in 4% w/v NaOH solution for one hour and pre-dried in an oven at 80 0 C for one hour before using them in composite fabrication.Specimens for mechanical testing were prepared based on ASTM D638, ASTM D3410, ISO 179:1997 and ASTM D790 standards. From the test results, the mechanical properties of alkali treated composites were found to be higher than those of untreated composites. For instance, the tensile, flexural and compressive strengths increased by 12.59%, 11.36% and 23.46% respectively while the tensile, flexural and compressive moduli of the composites increased by 31.19%, 12.97% and 34.98% respectively as a result of alkali treatment. This shows that alkali treatment of sisal fibres improves the mechanical properties of the resultant composites...

It is a very important physical parameter in polymer engineering affecting production cost and profitability of the manufacturing process. A reduction in density reduces the raw material cost hence decreases the manufacturing costs. Therefore, the aim of this research was to study the factors affecting density of locally made bio-resin from raw banana peels. The raw banana peels were washed, boiled, pureed and treated with various ratios of glycerin to obtain a thermoplastic bio-resin. The effect of temperature, time, resin quantity, glycerin and water on bioresin density were studied through use of the central composite rotatable experimental design and regression analysis. Second order polynomial regression equation for density was fitted and exhibited an R2 value of 83.4%. From the predictive model, it was evident that to obtain the objective of density minimization, temperature ...

The stalks are normally disposed of by burning, which contributes to the emission of harmful greenhouse gases which pollute the environment. Cotton stalks were collected from Umguza region in Zimbabwe which is located 53km from Bulawayo town. The stalks were subjected to retting for 3 weeks and there after fibre extraction carried out by means of manual decortication. The fibres were then subjected to a number of tests such as tensile strength, moisture regain, linear density, density and fibre length measurement test. The fibres were characterised according to their position relative to the cotton stalk and segmented as fibres from the top section, middle section and bottom section. The test results from characterisation of the fibres were analysed using SPSS statistical software. The cotton stalk fibres have a light brownish colour and the fib...

Therefore, it is paramount important to apparel industry to be flexible enough to respond quickly to the unstable customers' demand through continuous improvement of their process efficiency and productivity. This study aims at achieving an optimal trouser assembly line balancing using simulation-based optimization via design of experiment. The empirical study is conducted at Southern Range Nyanza Limited (NYTIL) garment facility and a complex trouser assembly line with 72 operations is considered. The discrete event simulation of the trouser assembly line is developed using Arena simulation software. The local optimal solution is obtained from simulation experimentation and is adopted for the optimization process. The OptQuest tool is utilized to solve a single objective function (throughput) optimization problem. The results show that average throughput increases from the existing design (490 pieces per day) to local optimal design (638) and global optimal design (762). Consequently, the line efficiency increases from 61.2% to 79.7% to 95.2% respectively. The high increase in line efficiency and average throughput confirms the suitability assembly line balancing using simulation-based optimization via design of experiment.

Ready-made garment industries have long historically adopted fewer technological and process advancement as compared to automotive, electronics and semiconductor industries. Simulation modeling of garment assembly line system has attracted a number of researchers as one way for insightful analysis of system behaviour and improving its performance. However, most of simulation studies have considered ill-defined experimental design which cannot fully explore the assembly line design alternatives and does not uncover the interaction effects of the input variables. Simulation metamodeling is an approach to assembly line design which has recently been of interest to so many researchers. However, its application in garment assembly line design has never been well explored. In this paper, simulation metamodeling of trouser assembly lin...

Currently, we have entered a new paradigm shift called industry 4.0 where science fictions have become science facts, and technology fusion is the main driver. Therefore, ensuring that any advancement in technology reach and benefit all is the ideal opportunity for everyone. In this paper, disruptive technologies of industry 4.0 have been explored and quantified in terms of the number of their appearances in literature. This research mainly aimed at identifying industry 4.0 key technologies which have been ill-defined by previous researchers and to enlighten the required skills of industry 4.0. Comprehensive literature survey covering the field of engineering, production, and management from both academia and business was done from publication databases: Google scholar, ScienceDirect, Scopus, Sage, Taylor & Francis and Emerald insight. The results of the stud...

Now, the race for the fourth industrial revolution (industry 4.0) is on and there is no option, every country whether developed or developing must participate. Many countries have positively responded to industry 4.0 by developing strategic initiatives to strengthen industry 4.0 implementation. Unlocking the country's potential to industry 4.0 has been of interest to researchers in the recent past. However, the extent to which industry 4.0 initiatives being launched globally has never been revealed. Therefore, the present study aimed at exploring industry 4.0 initiatives through comprehensive electronic survey of literature to estimate the extend of its launching in different regions. Inferences were drawn from industry 4.0 initiatives in developed nations to be used as the recommendations for East Africa Community. Results of the survey revealed that 117 industry 4.0 initiatives have been launched in 56 countries worldwide consisting of five regions. The country's percent of industry 4.0 initiatives as per region were: Latin America and the Caribbean (15%), North America (40%), Europe (53%), Asia and Oceania (25%), Middle East and Africa (11%). While the worldwide percent was estimated as 25%. This revealed that the big gap is existing between countries towards the race for industry 4.0.
