Why every engineering university in Bangladesh should teach reliability engineering

Bangladesh produces thousands of engineers every year, but too few are trained to answer a basic question for the country’s progress: how do we stop important systems from breaking down?

This is not an abstract idea. It becomes real when a transformer fails at peak demand, a pump station stops working in a flood, a factory line breaks down before goods can be shipped, a water treatment plant loses capacity, a hospital backup system does not work, a bridge wears out faster than planned, or a digital service goes offline when people need it. These failures cost money, disrupt public services, create safety risks and reduce national productivity.

That is why every engineering university in Bangladesh should teach reliability engineering.

Reliability engineering is the study of how to design, run, maintain and improve systems so they keep working as expected for as long as possible. It asks clear questions: what can go wrong, how likely is it, what happens if it does, how can we spot early warning signs, and what should we do before something fails? It links design, maintenance, data, safety, day-to-day operations and cost. In short, it teaches engineers not only how to build systems but how to keep them running.

Bangladesh’s growth so far has focused on building: roads, bridges, power plants, economic zones, treatment plants, buildings, ports and digital systems. Building is essential. The next stage of progress, however, depends more on performance. A power plant that keeps breaking down is not just an engineering issue. A water utility with high losses and frequent pump failures is not just a local problem. A factory with repeated equipment breakdowns is not just a maintenance issue. A data centre that cannot stay online is not just an IT issue. These are all reliability problems.

Yet reliability engineering is still missing or weak in many engineering courses.

Students learn circuit theory, machine design, thermodynamics, structural analysis, power systems, electronics, programming, fluid mechanics and control systems. These subjects matter. Students also need to understand how real systems fail in practice. They should learn about failure modes, preventive and predictive maintenance, root-cause analysis, asset management, spare-parts planning, condition monitoring, safety procedures, risk-based inspection and the full cost of an asset over its life. Without this, young engineers may leave university ready to calculate but not ready to keep systems working.

From my own work in power generation, water infrastructure, industrial automation, reliability engineering and data-centre operations, I have seen that the difference between a strong site and a weak one is rarely one machine. It is the discipline around the machine. Are alarms checked properly? Are maintenance records accurate? Are technicians trained? Are spare parts available? Are sensors calibrated? Are risks ranked? Are failures properly studied, or simply fixed and then forgotten? Reliability is a working culture before it becomes any software system.

Bangladesh needs that culture in its engineering universities.

Public safety is one clear reason. Failed infrastructure can put lives at risk. Poorly maintained electrical systems can cause fires or blackouts. Weak drainage and pumps can make flooding worse. Unreliable water and wastewater systems can harm public health. In transport, structural decay can create danger. Engineering courses should train graduates to look beyond design drawings and completion certificates. They should learn to ask how systems will perform after five, ten or twenty years of weather, load, corrosion, human error and limited budgets.

Economic strength is another reason. Bangladesh aims for stronger manufacturing, higher-value exports, better logistics, data centres, digital services and more varied industry. None of this can succeed on weak infrastructure. A factory loses money when machines stop without warning. A port loses efficiency when equipment downtime delays cargo. A power utility loses public trust when outages are common. A data centre loses credibility when it cannot stay online. Reliability engineering is not a narrow technical subject. It is an economic skill that reduces downtime, extends the life of assets, raises productivity and protects investment.

Better maintenance also matters. Bangladesh often spends large sums on new infrastructure but does not always maintain what it has built with the same care. Reliability engineering can help change that view. Students should understand that maintenance is not low-status repair work. It is a professional discipline based on risk, data, inspection, planning and clear responsibility. An engineer who prevents a pump failure, spots a transformer risk early or cuts production downtime can save more public and private value than many new project announcements.

Automation adds to the need. Modern infrastructure relies on sensors, SCADA systems, PLCs, digital meters, control panels, data historians, building management systems and computerised maintenance platforms. Engineers must know how to use the data these systems produce. A rise in vibration or temperature, a drop in pressure, unusual motor current, repeated breaker trips or a pattern of alarms can be an early warning. Reliability engineering teaches students how to read those signs and act before the public notices a failure.

Climate resilience is the final reason. Bangladesh faces heat, humidity, flooding, storms, salinity, waterlogging and other environmental pressures. These conditions shorten the life of infrastructure. An engineer trained in reliability thinks about how climate affects equipment, materials, electrical rooms, drainage, backup systems, access roads and emergency response. Climate resilience is not only about building embankments or writing policies. It is also about designing and maintaining systems that keep working when conditions are abnormal.

Universities should therefore make reliability engineering a core or required course for students in electrical, mechanical, civil, industrial and environmental engineering. Different departments can adapt the details to their own fields, but the shared foundation should cover failure modes, risk analysis, maintenance strategy, asset life-cycle management, condition monitoring, root-cause analysis and reliability measures. Practical laboratories should be set up around pumps, motors, drives, sensors, control systems, thermal imaging, vibration monitoring, power quality and industrial automation. Students should diagnose real faults, read maintenance data, interpret alarms and write corrective plans, not only solve textbook problems.

Partnerships with industry should form part of the course. Power and water utilities, factories, telecom operators, data centres, ports, hospitals and economic zones can supply case studies without sharing confidential details. Students can learn from actual failures: what went wrong, which warning signs were missed, what the repair cost, and how the same problem could have been prevented. Final-year projects should include reliability topics. Students could develop low-cost monitoring systems, predictive maintenance models, digital asset registers, pump-station dashboards, transformer-health tools, water-loss analysis, factory downtime studies or simple digital twin prototypes. Such work would be far more useful to Bangladesh than purely academic exercises that never leave the classroom.

Professional bodies and accreditation authorities should treat reliability engineering as a national skills priority. The country should check how many engineering programmes already offer courses in reliability, asset management, predictive maintenance or industrial maintenance, and should measure employer demand for graduates with skills in reliability, automation, SCADA and maintenance planning.

The aim is not to load students with another fashionable subject. The aim is to prepare engineers for the infrastructure Bangladesh already has and the infrastructure it wants to build. A country that is moving towards advanced manufacturing, AI systems, resilient utilities and digital public services needs engineers who can protect uptime, not only design new capacity.

Bangladesh has trained generations of engineers to build. It must now train the next generation to keep systems working. The country’s future will depend not only on how many bridges, power plants, factories, data centres and water systems it constructs, but on whether those systems continue to serve the public reliably long after the opening ceremony is over. Reliability engineering should not be a speciality learned only after people enter industry. It should be part of the engineering mindset from the start.
